2 Introduction
The Personnel Grounding Tester PGT®120 is an electronic test instrument for
checking personnel grounding systems such as wrist straps, coil cords and footwear.
The PGT®120 is suitable for compliance verification of the above products, according
to the IEC 61340-5-1 Edition 1.0 (2007-08) or ANSI/ESD S 20.20 – 2007 (2007-03).
The unit operates with 3 independent measuring circuits for the left shoe, the right
shoe and the wrist strap. This makes it possible to measure all the values at the
same time
It is possible to enable or disable separately the measuring circuits.
The order of tests is random.
Footwear measurement can be configured to measure in series with hands free
for passenger gates.
Visual and audible test results and a dry relay contact for door opener
Use the optionally available "Calibration Unit " Part No. 7100.PGT120.CU to
check the unit Hi and Lo limit values
2.1 Device return and environmentally compatible
disposal
The instrument is a category 9 product (monitoring and control instrument) in
accordance with ElektroG (German Electrical and Electronic Device Law). This
device is not subject to the RoHS directive.
We identify our electrical and electronic devices (as of August 2005) in
accordance with WEEE 2002/96/EG and ElektroG with the symbol shown to
the right per DIN EN 50419.

3 Installation
The Unit is for desktop or wall mounting. The optionally available wall mounting
frame (Part No. 7100.PGT120.WK) can be used to fix the unit to a wall.
The power is either supplied by a 9V battery or by a power supply. Insert the
batteries by opening the battery compartment flap on the bottom side of the unit.
Take care of the proper polarity. Close the battery compartment flap again.
It is strongly recommended to remove old or empty batteries to avoid battery
leakage.
For heavy use or footwear in series mode, we recommend using the external power
supply. Use only an original power supply connected to the "AC12V" socket on the
rear. On plugging in external power, the internal battery is disconnected.
The battery should be removed to avoid wear out.
Do not connect any conducting articles with PGT®120 exept original accessories
(power supply, battery and foot wear electrode) and the door opener.
Connect the foot electrode with the coloured marked plugs to the back of the unit for
footwear test.

4 Operation
This tester has no power switch. Pressing an electrode or activating "footwear in
series" activates the electrical circuit.
The measuring voltage is preset to 100V. Use the DIP switches 6+7 to adjust the
voltage to either 30V or 50V.
4.1 Wrist strap test
Put on the wrist strap and connect it via a coil cord to the snap or to the socket on the
left side of the unit.
Press the left electrode and keep it pressed. A peep signal indicates the start of
measurement. After a short measuring time the result is displayed.
Release the electrode.
4.2 Coil cord test
To check only the coil cord, connect the coil cord to the 3mm snap located inside the
wrist strap symbol and to the 10mm snap or socket on the left side of the unit.
Press the left electrode and keep it pressed. A peep signal indicates the start of the
measurement. After a short measuring time the result is displayed.
Release the electrode.
