Override Test Range Voltage Button
The button is a switch, which if depressed will override automatic voltage selection and test will be
performed at 10 volts regardless of resistance level.
When in the “up” or Auto position, during resistance portion of test, meter will automatically switch to
the correct voltage for the resistance range. A function LED will light to indicate selected voltage.
Conductive material 10
5 ohms or less is measured at 10 volts. Dissipative material 10 6 ohms or
greater is tested at 100 volts.
Jacks
The left hand jack on the meter accepts a shielded 3.5mm plug. The right hand jack accepts a
standard banana plug.
Test Leads
One end of the black test lead provided is terminated with a 3.5mm plug and fits the left meter jack.
The 3.5mm plug is shielded per ESD S4.1 (Refer to RTG test procedure later in this manual.) The
other end of the black test lead and both ends of the white test leads are terminated with a standard
banana plug.
Battery Replacement
The battery compartment is located in the bottom end of the unit. Depress the two buttons on the
sides of the bottom end cap and remove cap. Press on the right edge of the protruding battery door
to unlatch it and swing the door open. Observe polarity and carefully replace the batteries with
alkaline Type AA. Polarity must be correct or damage may occur. Close battery door and reinstall
bottom end cap onto meter case.
Cleaning and Maintenance
Work surfaces or material to be tested should be cleaned prior to testing to ensure that surface dirt
and contamination do not affect the test results. Periodically clean the two 5-pound conductive
rubber probe electrode surfaces. Use solvent free rubber cleaners. We recommend using an anti-
static cleaner or Stat Wipes, pre-saturated cleaning wipes. Make sure the surface is dry before
testing.
The 292 Surface Resistance Test Kit requires little maintenance with no user serviceable parts. If
your meter requires service beyond cleaning the electrodes or changing the batteries, please contact
the factory.
Calibration
Monroe Electronics instruments are factory-calibrated prior to shipment. Recalibration should be
performed annually, or more frequently if specified by contract or company policy. Your instrument
should also be recalibrated any time it has been repaired or tampered with. We are happy to
recalibrate your instrument for you at a reasonable cost, or provide information and procedures on
calibration upon request.
