Figure 1. 19635 : Meg Pocket Megohmmeter
Description
The Desco 19635 :Meg Pocket Megohmmeter is a
portable test instrument designed for measuring both
surface and surface-to-ground resistance of static
dissipative and conductive materials. Seven color-
coded LEDs, read from right to left, easily identify static
dissipative and conductive ranges. The :Meg will test
materials with surface resistivity of 1x10
This test instrument is ideally suited for Quality Control
and Field Service personnel as well as for use in
routine auditing of your ESD protective materials. The
:Meg features simple one-button operation and a 9V
battery for ease of use and maximum portability. This
auto-ranging instrument weighs only six ounces. The
high-impact plastic case ensures durability despite the
meter's light weight.
The :Meg has not been designed to meet ESD S4.1
test equipment requirements and therefore
measurements obtained with this device may not agree
with measurements taken according to the ESD S4.1
test procedure. This test instrument is intended for use
only as an auxiliary tool for monitoring surface
resistance performance.
If you are interested in obtaining a meter which does
meet all the test equipment requirements of ESD S4.1,
we recommend our model 19780 Surface Resistance
Test Kit. For more information on this product ask for
Techical Bulletin TB-3014.

Installation
Remove the meter from the carton and inspect for
damage. Each unit should be fully charged and
includes:
1 :Meg Pocket Megohmmeter
1 Surface-to-Ground, cord assembly
1 Installed 9V battery
Properly store the megohmmeter and its component
assemblies when not in use.
Operation
The :Meg will perform Surface Resistivity and Surface-
to-Ground resistance measurements. Work surfaces
and materials to be tested should be cleaned prior to
testing to ensure that surface dirt and contamination do
not affect results. It is recommended that non-silicone
and non-alcohol based cleaners such as Desco's
Reztore™ Surface and Mat Cleaner be used for
regular cleaning of ESD protective work surfaces.
When non-ESD surfaces are being used, Reztore™
Topical Antistat is recommended for eliminating static
charge generation.

Surface and Surface-to-Ground resistance readings
are indicated by the series of LEDs on the face of the
mater. The LEDs are read from right to left as follows:
1. RED – >10
2. RED – Less than 1 x 10
3. GREEN – Less than 1 x 10
4. GREEN – Less than 1 x 10
5. GREEN – Less than 1 x 10
6. YELLOW – Less than 1 x 10
7. YELLOW – Less than 1 x 10
