Installation

What you have received

You should have received the following major components:

• An instrument, model 3658/418R, with keypad, display, and handle

• A membrane-covered thermal conductivity (TC) sensor, model 31478

• A flow chamber, model 32058 with flow adjustment valve

1 Sample flow inlet 7 Battery cap

2 Flow rate adjustment valve 8 Purge gas (air) inlet

3 Flow chamber 9 Flow chamber locking nut

4 Sample flow outlet 10 TC sensor

5 Pressure relief valve 11 Purge gas (air) outlet

6 RS-232 port and DC power connection 12 Sensor locking pin

The ORBISPHERE 3658 portable analyzer accurately measures carbon dioxide in dissolved phase,

using a thermal conductivity sensor. The analyzer can store up to 500 measurements, and its

rechargeable batteries allow up to 15 hours continuous operation.

Before each measurement the TC sensor is automatically flushed with ambient dried air supplied by

the integrated pump and condenser, and sucked into the flow chamber through the purge gas inlet

(No. 8 in Figure 1) before being released back into the atmosphere via the purge gas outlet (No.

11 in Figure 1).

After each purge, the gas to be measured diffuses from the liquid sample through the membrane,

changing the thermal conductivity of the gas surrounding the detector. As each gas has its own

specific thermal conductivity the measurement is not affected by the presence of other gases unlike

traditional total pressure/temperature methods. The liquid sample flow rate is adjustable using the

flow rate adjustment valve (No. 2 in Figure 1) integrated into the flow chamber.

Both the membrane-covered TC sensor (No. 10 in Figure 1) and the flow chamber (No. 3 in Figure 1)

are shipped pre-installed on the instrument. It will, however, be necessary to remove the flow

chamber when servicing the sensor.

3658 PC software installation

Install the Hach 3658 software by inserting the accompanying CD into your PC and running the

SetUp program. Simply follow the on-screen instructions.

When finished, a new directory HU\HU3658 is created on your hard disk containing the software and

help files.

6 English

Atmospheric pressure equilibrium

As soon as you receive the instrument, it will be necessary to ensure the interior and exterior of the

instrument are both at the same atmospheric pressure. It is probable that during shipment these

pressures will become different.

To ensure the pressures are equal, simply press the pressure relief valve located on the top of the

instrument (No. 5 in Figure 1 on page 6) for about 5 seconds before releasing.

Connections

Flow chamber

The flow chamber’s sample inlet (N° 1 in Figure 1 on page 6) and outlet (N° 4 in Figure 1 on page 6)

use ¼-inch diameter transparent plastic tubing. Connect by compression fittings to the sample

source and to the drain, respectively.

Control the sample flow using the adjustment valve (No. 2 in Figure 1 on page 6) located on the front

of the flow chamber.

If ordered, you will also have received a model 32051 sample tube adapter to attach the flow

chamber inlet tubing to the sampling point.

Instrument - PC connection

An RS-232 cable is supplied with the instrument, with a 6-pin LEMO plug on one end and a 9-pin D-

Note: If you use an adapter for the connection to the PC, make sure it is designed for this purpose and, thus, has

all nine pins accessible. Some 25-to-9 pin adapters are supplied for specific use, such as a mouse, and these may

have only certain pins available.

It is not necessary to keep the PC connected to the instrument during measurement. This connection

is required for downloading stored measurements, real-time monitoring, reviewing and changing

configuration parameters and testing the instrument from the PC.

External power supply (optional)

The instrument is usually powered by the batteries supplied. You can, however, power it from an

external power source using the model 32939 power supply adaptor as illustrated in Figure 2.

English 7

Figure 2 Model 32939 power supply

Connect the male LEMO-6 plug on the power supply adapter, to the RS-232 connector on the right

side of the instrument. The female LEMO-6 plug can then be used to connect to your PC using the

standard RS-232 cable supplied with the instrument.

Plug the transformer into your mains power supply using the cable supplied.

Note: If the external power supply is not clean, this may result in unstable measurements.

Instrument location

Locate the instrument close to the sample being analyzed, and to the PC if one is being used. A

LEMO-6 connector for RS-232 serial output to a PC is on the right side of the instrument (No. 6 in

Figure 1 on page 6).

Make sure you install a fully charged set of batteries, or connect the instrument to an external power

source (see External power supply (optional) on page 7 for details) before switching the instrument

on and exposing the sensor’s membrane to any liquid.

Installation checklist

Power

The instrument is designed to work on battery power or an external power supply.

If battery power should drop, a [LO BAT] warning appears in the instrument LCD's top left corner,

and they should be replaced.

If using an external power supply, ensure that this is clean, otherwise it may result in unstable

measurements.

Clock setting

If you use the instrument to store measurements for downloading to a PC, you should verify the date

and time settings of the instrument's internal clock, as described in Clock settings on page 24.

Barometric pressure setting

The internal barometric pressure sensor has been factory calibrated but should be verified on-site

with a precision certified barometer, and corrected if necessary. For instructions on how to do this,

please refer to Barometric pressure sensor calibration on page 17.

Flow chamber

The flow chamber inlet and outlet should be free of any obstructions.

When analyzing carbonated beverages, sufficient pressure must be provided to avoid degassing of

the beverage during its passage through the flow chamber. Check for the absence of bubbles in the

inlet tubing.

If necessary, adjust the pressure using the flow adjustment valve.

Operating Instructions

N O T I C E

To avoid damaging the sensor, never remove the flow chamber during normal operation. The flow chamber

should only be removed during service procedures.

Operating controls

The front panel of the instrument has a three-digit liquid crystal display (LCD). The LCD includes a

right-side marker to distinguish between gas concentration and temperature display. This marker

also indicates the measurement display units (g/kg, V/V, etc.) depending on the instrument

configuration. To the LCD's right is a label showing the measurement units configured at the factory

for your application.

In addition to the controls indicated on the front panel, there is also a pressure relief valve on top of

the instrument. Refer to Instrument overview on page 6. This button need only be pressed as part of

the installation procedures, and/or if pressure builds up inside the instrument due to large

temperature changes.

The panel keyboard has the following push-button controls:

Power switch. This turns instrument power on or places in standby. When switched on, the

instrument performs a series of start-up procedures before switching to measurement mode

Places the instrument in measurement mode

Calibrates the analyzer against a reference sample. This button can be locked out from the Hach

3658 PC program

Stores a measurement value into memory

Backlights the LCD for approximately three minutes. Push repeatedly to increase the backligth to

the maximum value and back to minimum.

Toggles between gas concentration and temperature measurement displays in measurement

mode, increases or decreases the storage number during storage or memory view, or sets a

calibration value during calibration

You can access other instrument functions by pushing one of the following keys while also pressing

the power button:

English 9

Selects dissolved or gaseous measurement phase. Refer to Gas measurement phase

on page 15.

Start automatic data acquisition. Refer to Automatic data acquisition on page 11.

Start memory storage view .Refer to Viewing stored measurements on page 12.

Starts continuous purge mode. Refer to Continuous purge on page 25.

Display program identification information

Once you have completed the installation and start-up procedures defined in Installation on page 5,

the analyzer can be operated independently, making measurements as a portable carbon dioxide

gas analyzer.

You may store these measurement values for later analysis via the Hach 3658 program (on your

personal computer) or the memory view mode (on the instrument). The Hach 3658 program

operation is described in detail throughout the manual, where relevant.

Taking measurements

To start the analyzer, press the POWER switch (located bottom left of the keyboard). When you turn

power on, the instrument displays the software version number briefly, and then starts a series of

start-up tests. This process should take only a few minutes, during which time a [tSt] message is

displayed on the LCD. Once the tests are completed, a clearing message [---] is displayed for a

further sixty seconds before the instrument switches automatically to measurement mode.

Note: The start-up tests will be repeated until successful, or for a maximum of 15 minutes. If the tests are still

unsuccessful after 15 minutes, a [Err] message will be displayed and the instrument locked. Turn the instrument off

and retry the start-up procedures, but if the problem persists, please contact your local Hach Lange service

representative for assistance.

Measurement updates are displayed every 20 seconds, and it is normal for the right-most digits to

vary in reaction to slight variations in gas content. For accurate measurements, the sensor's

membrane must be at the same temperature as the sample to be analyzed. If this not the case, allow

some sample to pass through the flow chamber for about 3 minutes before taking any

measurements.

The LCD includes a right-side marker to distinguish between gas concentration measurements and

temperature. This marker also indicates the measurement display units (k/kg, V/V, etc. depending on

the instrument configuration).

To switch between gas measurement and temperature measurement, press the Up/Down Arrow

buttons. To illuminate the LCD for approximately three minutes, press the Backlight button.

Select gas measurement phase

Ensure the gas measurement phase is correct for this measurement. For details on viewing the

current setting, refer to Reviewing instrument configuration on page 15. For details on changing

this setting, refer to Gas measurement phase on page 15.

Measurement mode

You can set the measurement mode to normal or maximum. For details on how to do this refer to

Measurement mode on page 17.
