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 either 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 between each other. Take into account that in a substation you will find, in disconnected points, high potential levels in relation to the earth/ground point. Those potentials are caused by presence of electromagnetic fields and can be minimized following the indications in the paragraph before.
• Make sure that the current connections are well connected to avoid undesirable heating.
• 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 modification must be made, press the STOP button first.
• The micro-ohmmeter should never be used in an explosive environment (this includes 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 specifications.

Keypad and Function Buttons

The Model 6292 can be operated and configured 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 configuration 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 configuration and instrument settings.
• DEL erases characters.
• SAVE saves the configuration 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.

• 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.

During a fixed current test, a short press will allow manual adjustment of the test current.

Getting Started

1.  Connect the instrument to a 120/240V 50/60Hz AC power supply.
2. Perform a test with the test leads shorted. If the current does not reach the preset current (or the measured resistance is significantly higher than 0W), check the connection and try again. If the problem persists, contact technical assistance.
3. Before turning the instrument on, connect the test probes to the device to be tested and to the appropriate front panel terminals

Connection Example in BSG Mode:

WARNING: 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 final result.
• If the Auto Save function in the menu settings is set to ON, the final result will be automatically saved at each successfully completed test.
