1.3 Operation and maintenance advice

1.3.1 Battery changing

If the display shows the “BAT” segment, the battery needs chang-

ing. After showing the “BAT” segment the instrument has approx.

1 hour of battery life remaining.

A 9 Volt Dry-cell battery is used for the instrument power supply. To

change the battery, switch o the instrument and open the battery

cover on the rear of the instrument. Remove and disconnect the

battery from the instrument. Connect a new 9 V battery to the plug

and put the battery back into the instrument.

To protect the environment please don’t dispose

of batteries with household waste, but use

separate disposal.

If the device is not going to be used for some time, we advise that

the battery is removed.

1.3.2 Battery changing of the CTH65I0

The exchange of this maintenance element

may only be carried out outside of the

hazardous area. Take care and ensure that

when changing the battery, that only those

in the listed operating instructions are used.

The use of any other type of battery is strictly

forbidden in that it will invalidate the Ex-data

certication.

1.3.3 Connecting/Changing temperature sensors

■

Only use the delivered temperature sensors! For a sensor

exchange, switch o the instrument. Plug in the sensor before

switching on the instrument, or otherwise it may occur that the

sensor is not properly identied by the instrument.

Digital indicator and temperature sensor are connected using

a discrete connecting cable. When changing the temperature

sensor, always connect and disconnect at the sensor end of the

cable.

To connect the sensor, rotate the plug till it locates in the guide

slot, allowing it to plug in.

Stecker nicht verkantet anstecken. If the plug is correctly located,

it will slide in smoothly. To disconnect the sensor hold it by the plug

to release the connector lock. Do not pull the cable to release it.

ment carriage paid to WIKA.

1.4 Operation

Before switching on the instrument, connect the probe/s to the

instrument and insert the battery (Please refer to chapter “1.3.1

Battery changing“). A number on the instrument’s housing marks

each port.

1.5 Switching ON and OFF

The instrument is switched On or O by pressing the ON/OFF

key. After switching on the instrument indicates a full segment

test for 1.5 sec., afterwards the instrument shows the calibration-

code and the adjusted measurement category for channel 1.

(Only 2-channel instruments: After a further 1.5 sec. the instru-

ment shows the calibration-code and the adjusted measure-

ment category for channel 2.) in the instrument then reverts to

measurement mode, indicating the actual measurement value (for

example: temperature). All instruments display the measurement

value of channel 1 in the top display line (large digits). Directly

below you will see the trend bargraph. For 2-channel instruments

the meas ured value of Channel 2 is displayed on the bottom line

(small digits).

Fig 1: Example of display after switching on.

channel 1

Line 1: [oFF P = calibration code of channel 1

according to standard linearization (DIN), probe

selection of channel 1 = Pt100.

channel 2

Line 2: [oFF P = calibration code of channel 2

according to standard linearization (DIN), probe

selection of channel 2 = Pt100.

On all instruments you can select the measure-

ment category (chapter “2.1.2 Probe selection

[Prob]”) according to the model version. Instru-

ments that are delivered with only one probe have

the correct measurement category preset. For all

other cases please check chapter “2.1.2 Probe

selection [Prob]” for the correct set-up.
