Body Voltage Meter
Installation, Operation and Maintenance
Description
The Statguard Flooring D19431 Body Voltage Meter
is a portable measuring system that allows analysis
of charge levels accumulated on the human body
according to ANSI/ESD STM97.2. The Body Voltage
Meter measurement may be logged using internal
memory. Logged measurements can be exported and
further reviewed on a PC. Graphs of measurements can
be displayed on the LCD display for quick evaluation.
Each Body Voltage Meter is calibrated with accepted
procedures and standards traceable to the National
Institute of Standards and Technology (NIST) and
includes a NIST certificate.
November 2020
“A compliance verification plan shall be established to
ensure the organization’s fulfilment of the requirements
of the plan. Process monitoring (measurements) shall be
conducted in accordance with a compliance verification
plan that identifies the technical requirements to be
verified, the measurement limits and the frequency at
which those verifications shall occur. The compliance
verification plan shall document the test methods
used for process monitoring and measurements. If the
organization uses different test methods to replace
those of this standard, the organization shall be able
to show that the results achieved correlate with the
referenced standards. Where test methods are devised
for testing items not covered in this standard, these shall
be adequately documented including corresponding
test limits. Compliance verification records shall be
established and maintained to provide evidence of
conformity to the technical requirements. The test
equipment selected shall be capable of making the
measurements defined in the compliance verification
plan.” (EN 61340-5-1 clause 5.2.4)

COM Mode Operation
Using the Meter
1. Press the EXIT button to power the meter.
2. Hold the test probe and momentarily touch the
ground touch plate located on the back of the unit.

ground the operator
Exports data to PC using supplied 8-Pin DIN to USB
cable.
Installation
1. Remove the meter from the carton.
2. Connect the included ground cord to one of the
two ground jacks located at the top of the meter.
Connect the opposite end of the ground cord to
equipment ground.
3. Connect the test probe to the probe connector
located at the top of the meter.
4. Press the EXIT button to power the meter.
5. NOTE: The electronic components of the
electrostatic sensor require a warm-up period
of 5 minutes to obtain accurate and stable
measurements. The sensor uses a vibrating
element to perform measurements, and the
warm-up period allows its mechanical assembly
to stabilize. An exclamation mark symbol on the
display and an audible sound will alert the operator
once warm-up has been completed.
Figure 3. Setup of the Body Voltage Meter
3. Verify the Body Voltage Meter is zeroed by toggling
to the MONITOR menu and reading the measured
value. It should be 0 V. Zero the Meter if required by
toggling to the ZERO menu.
Monitor Mode
1. Toggle to MONITOR mode on the meter, and press
the Start / Stop button.
2. The display will show the electrical potential present
on the probe.
3. A beeping sound (every second) indicates that the
meter is measuring. This is to ensure the unit is not
left in measuring mode unintentionally and cause
the battery to drain.
4. To stop the measuring process, press the Start /
Stop or Exit buttons.
6. The meter is now ready for use.
