Description
Ohm Metrics Pocket Resistance Meter:
SRM 310
This SRM 310 uses parallel electrodes and concentric
rings to accurately measure RTT, RTG, or resistivity for
periodic verification, factory audits or test lab evaluation
of product.
This meter is designed to verify incoming materials such
as floor mats, table mats, bins and shelving in static con-
trolled areas. Work surfaces, bags, wrist straps, footwear,
packaging materials, garments, and ESD chairs can also
be tested with the device.
The SRM310 meets periodic test requirements per Com-
pliance Verification ESD TR53 and conforms to ANSI/EOS/
ESD (S4.1, S7.1, S12.1, S2.1).
Ohm Metrics test and measurement products, from
Transforming Technologies, are useful, reliable tools for
characterizing and identifying the electrical resistance of
materials and the performance of personal grounding
products.
All Ohm Metrics products are designed to support
ESDA Compliance Verification TR53.
All Ohm Metrics products can be calibrated.
All Ohm Metrics test and measurement products are
warranted for 1 full year.

Operation
Battery Installation
Remove screws from back cover using a Phillips style screw
driver and detach from monitor. Insert the included 9 volt
battery, replace back cover and secure with screws.
Only new and valid batteries can be used.
Low battery power is indicated when the last Red LED
flashes during measurement. Stop testing and replace
with fully charged 9v battery.
Measuring Surface Resistance
1. To measure the surface resistance of an object, hold the
instrument to the surface and press the TEST” button.
2. The value is indicated by colored LED lights.
3. Refer to “LED Indication Guide” on Page 4 for LED.
Other Measurements
By connecting the optional SR0055,Surface Resistance
Probes, it’s possible to measure other forms of resistance
such as “point to point” resistance ,or “volume resistance”.
Contact Transforming Technologies for Surface Resistance
Probes, Model number: SR0055.

Measuring Resistance to Ground
For surface resistant probes:
1. Plug in the supplied grounding cord into socket of the
meter. The associated internal electrode is now discon-
nected.
2. Connect the opposite end of the grounding cord to
“ground”.
3. Use Steps 1-3 in “Measuring Surface Resistance” to
complete the test.
Measuring Resistance Between Two Points
Note: Must have surface resistant probes:
1. Position the two 5lb probes 3 ft. away from the surface
to be measured.
2. Attach the 3.5mm leads to meter and connect the ba-
nana plug to probes.
3. Press power button to test.
NOTE: The voltage will automatically change to either 10v
or 100v depending on the resistivity of the material.
Refer to the EOS/ESD Specifications. EOS/ESD-S4.1, ANSI
-ESD S7.1 and EOS/ESD-S11.11-1993

Calibration
The recommended calibrating interval is 12 months.
Notice
This instrument is not approved for measurements in explo-
sion hazard areas. High electrostatic charges or measuring
highly charged materials might damage the instrument.
Using the instrument in power plants is not permitted.
LED Indication Guide
The LED lights on the meter indicates how much resistance a
surface has and if it is “Conductive”, “Dissipative” or
“Insulating” by flashing colored LED lights.
Alarm Indications
Display Resistance Indicates
GREEN <-105K Conductive
YELLOW 106-1011 M Dissipative
RED 1012 M-> Insulating
