supply (< 1000 V).

Example: primary overcurrent protection devices, ripple control units,

and meters.

CAT III: Corresponds to measurements performed in the building installation

at the distribution level.

Example: hardwired equipment in xed installation and circuit

breakers.

Precautions for Use

The protection obtained by the instrument can be compromised if it is used in a

way that is not recommended by the manufacturer.

Do not attempt to perform any tests with this instrument until you have

read the user manual.

Tests are to be carried out on de-energized circuits only! Never connect

the unit to a live circuit.

The micro-ohmmeter must be connected to the earth/ground point

through the ground terminal or the power cord.

Be sure the power cord is accessible at all times, in case the instrument

needs to be quickly unplugged for any reason. Always disconnect the

power cord before performing any repair on the instrument.

Do not obstruct the intake vents or the fan to avoid overheating.

During a circuit breaker measurement, its contacts must be closed and

connected to an earth/ground point. The end connected to an earth/

ground point must be connected to the “C-” terminal.

Ensure the terminals are free of any voltage in relation to earth/ground

point and the other terminals. In a substation, you will nd high potential

levels in relation to the earth/ground point in disconnected points. Those

potentials are caused by presence of electromagnetic elds and can be

minimized following the indications in the paragraph above.

Make sure that the current connections are well connected to avoid

potential overheating.

Be careful when manipulating the current terminals in the instrument.

High temperatures may occur in the current connections.

Never connect or disconnect the cables during a measurement. If a

modication must be made, press the STOP button rst.

The micro-ohmmeter should never be used in an explosive environment,

such as poorly ventilated battery rooms and enclosures.

The instrument, test leads, and measuring wires must be free of defects

and should be changed if there is any evidence of deterioration (insulation

split, burnt, etc.).

Never exceed the safety values indicated in the specications.

Keypad and Function Buttons

The Model 6292 can be operated and congured using the alphanumeric

keypad. The keypad enables you to name objects (groups of tests) and enter

the date/time, and the function buttons let you select a number of conguration

settings.

The function buttons perform as follows:

CAPS LOCK when enabled (indicated by a green LED just above it)

results in all typed letters appearing capitalized on the display.

NUM LOCK when enabled causes the keypad to print numbers vs letters.

MENU displays the main menu for conguration and instrument settings.

DEL erases characters.

SAVE saves the conguration or advances one menu level.

ESC aborts some functions or returns back one menu level.

MODE selects between Normal or BSG (both sides grounded) modes.

START starts a test.

STOP stops a test.

Rotary Knob

The rotary knob has two primary purposes: (1) adjust the current during a test,

and (2) navigate through menus and select options.

During a xed current test, a short press will allow manual adjustment of the

test current.

When the main screen is displayed, a short press will perform the MENU

button function.

When in a menu, rotating the knob navigates through listed options; a short

press selects the highlighted option.

When in a menu, pressing the rotary knob for two seconds performs an ESC

button function.

Installing DataView®

NOTE: DO NOT CONNECT THE INSTRUMENT TO THE PC BEFORE

INSTALLING THE SOFTWARE AND DRIVERS.

1. Insert the USB stick into an available USB port (wait for driver to be

installed).

2. If Autorun is enabled, an AutoPlay window should appear. If Autorun is

disabled, it will be necessary to open Windows Explorer. Then, locate and

open the USB stick drive labeled DataView to view the les on the drive.

3. In the AutoPlay window, select Open folder to view les.

4. Double-click on Setup.exe from the opened folder view to launch the

DataView®setup program.

NOTE: For more information on using the DataView®software, refer to

the Model 6292 user manual that is supplied on the USB stick.

Getting Started

WARNING: Read the user manual and safety warnings before using

this instrument. Safety procedures and rules for working near high

voltage energized systems must be observed during the use of this

instrument. The generated voltages and currents may be dangerous.

1. Connect the instrument to a 120/240 V 50/60 Hz AC power supply.

2. Before turning the instrument on, connect the test probes to the appropriate

front panel terminals on the device to be tested.

3. Perform a test with the test leads shorted. If the current does not reach the

preset current (or the measured resistance is signicantly higher than 0 Ω),

check the connection and try again. If the problem persists, contact technical

support.

Connection Example in BSG Mode:

10 Micro-Ohmmeter Model 6292 - Quick Start Guide

WARNING: Read Do not connect or disconnect the test leads during

a measurement. Grounding connections are strongly recommended to

protect the operator and equipment. Use a strong grounding point as

close as possible to the device under test. This ground is required to

verify the instrument is working properly.

Saving a Test

To save a test result, press SAVE during the test to get partial results or

at the end of the test to save the nal result.

If the Auto Save function in the menu settings is set to ON, the nal result

will be automatically saved at each successfully completed test.

Establishing Communication to the Instrument

1. Connect the instrument to the PC with the supplied cable.

2. Double-click the Micro-Ohmmeter icon in the DataView folder that was

created on the desktop during software installation to open the Control

Panel.

3. From the menu bar, select Instrument,then click Connect to open the

Connection dialog box.

The instrument name should appear in the Communication port eld. If not,

select it from the drop-down list. Ensure that the Instrument model eld is

set to 6292, and the Communication rate is set to 57600. Then, click OK.
