Monroe Model 292A Digital Surface Resistance
Test Kit is a portable, versatile, instrument designed to accurately measure resistance between
two points (Rtt), surface to ground (Rtg), and
surface resistivity in accordance with ANSI/ESD
Association standard S-4.1. In addition, the
meter measures ambient temperature and relative humidity.
The Surface Resistance Meter (included in
the kit) is designed to make measurements in
accor-dance with specified test methods on:
Work surfaces – ANSI/ESD STM S4.1 Work
surfaces – Resistance Measurements
Floors – ANSI/ESD STM S7.1 – Resistive Characterization of Materials Floor Materials
Footwear – ANSI/ESD STM S9.1 – FootwearResistive Characterization
Garments – ANSI/ESD STM 2.1 Garments
Seating – ANSI/ESDESD STM 12.1 Seating –
Resistive Measurement
Floor/Footwear – ANSI/ESD STM 97.1 Floor
Materials and Footwear Resistance Measurement in Combination with a Person
Workstations – ANSI/ESD-AVD53.1 ESD Protective Workstations
•
high, liquid crystal display provides easy to read
measurements directly from the meter. No interpretations or calculations are required.
LED Displays: Surface resistance exponents
are displayed via 12 light emitting diodes (< 103
- >1012). LEDs are color coded for quick check
recognition: Five additional Function LEDs identify the measurement taken when lit.
Auto/10 Volt Hold Test Range Voltage Button:
When in the “up” or Auto position, during resistance portion of test, meter will automatically
switch to the correct voltage for the resistance
range. When in the “down” or 10 Volt Hold position automatic voltage selection is overridden
and the test is performed at 10 Volts regardless
of resistance level. An LED illuminates to note
selected voltage.
Test Push Button: Activates electrical power to
the meter. Quick Check Button: When set to FULL, the
meter will cycle through the 15 second electrification period that displays the temperature and
relative humidity before the surface resistance
mantissa is displayed. When set to QUICK, the
meter will skip the 15 seconds and immediately
display the surface resistance mantissa.
Ambient Temperature, Relative Humidity and
• Temperature in degress F (+/- 10%)
• Temperature in degrees C (+/- 10%)
• Relative Humidity as a percentage (+/- 10 integers)
• Surface Resistance Mantissa (with expo-
nent displayed via LED, measurement ex
pressed in ohms.)
Surface Resistivity:
Resistivity measurements require incorporating our optional resistivity adapter model 292/41.
The Surface Resistance Test Meter attaches easily too the resistivity adaptor. Parallel conductive
silicone rubber electrodes provide for measurement of surface resistivity.
The adapter is optional and must be specified separately when ordering, (292A/41 p/n
0930245.)

The 292A Surface Resistance Kit requires little
maintenance. Containing no user serviceable parts, only
careful cleaning of the electrodes and replacement of the
batteries is required.
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.
Warranty:
Monroe Electronics, Inc., warrants that each
instrument and sub-assembly manufactured by them shall be
free from defects in material and workmanship for a period of
two years after shipment from the factory. This warranty is
applicable to the original purchaser only.
