Introduction
The Personnel Grounding Tester PGT120 is an electronic test instrument for checking
personnel grounding systems such as wrist straps, coil cords and footwear. The PGT120 is
suitable for compliance verification of the above products, according to the IEC 61340-5-1
Edition 1.0 (2007-08) or ANSI/ESD S20.20-2007 (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

Installation
The Unit is for desktop or wall mounting. The optionally available wall mounting frame (Part
No. 7100.PGT100.101) 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 PGT120 except 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.

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 4+5 to adjust the voltage to
either 30V or 50V.
Wrist strap test
► Settings: Only wrist strap or OR is activated (DIP switch 1+2)
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.
OK Green LED flashes The measured value is o.k.
Hi-Fail Red LED flashes,
audible signal Above the resistance upper limit
Lo-Fail Red LED flashes,
audible signal Below the resistance lower limit
(not applicable if lower limit is disabled)
Release the electrode.
Coil cord test
► Settings: Only wrist strap or OR is activated (DIP switch 1+2)
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.
OK Green LED flashes The measured value is o.k.
Hi-Fail Red LED flashes,
audible signal Above the resistance upper limit
Lo-Fail Red LED flashes,
audible signal Below the resistance lower limit
(not applicable if lower limit is disabled)
Release the electrode.
Footwear test (single shoe)
► Settings: Only footwear or OR is activated (DIP switch 1+2)

Stand on the foot electrode, then press the right electrode and keep it pressed. A peep
signal indicates the start of measurement. After a short measuring time the result is
displayed.
OK Green LED flashes The measured values of both shoes are o.k.
Hi-Fail
right Red LED flashes,
audible signal Right shoe above the resistance upper limit
Hi-Fail
left Red LED flashes,
audible signal Left shoe above the resistance upper limit
Lo-Fail
right Red LED flashes,
audible signal Right shoe below the resistance lower limit
(not applicable if lower limit is disabled)
Lo-Fail
left Red LED flashes,
audible signal Left shoe below the resistance lower limit
(not applicable if lower limit is disabled)
Release the electrode.
Wrist strap and footwear test
► Settings: AND function is activated (DIP switch1+2)
Put on the wrist strap and connect it via a coil cord to the snap or socket on the left side of
the unit.
Stand on the foot electrode, then press one electrode and keep it pressed. A peep signal
indicates the start of measurement. After a short measuring time the result is displayed.
OK Green LED flashes All measured values are o.k.
Hi-Fail Red LED flashes,
audible signal Above the resistance upper limit
Lo-Fail Red LED flashes,
audible signal Below the resistance lower limit
(not applicable if lower limit is disabled)
Release the electrode.
The OK signal only appears when all measured values are within the limits.
Footwear in series
► Settings: Footwear in series activated (DIP switch 6)
► Limitation: The upper limit values cannot be changed in this mode
The footwear test can be accomplished hands free, without touching a electrode. This is
useful in combination with passenger handling gates. The resistance is measured between
the two shoes. This mode cannot directly indicate the faulty shoe. Press the Shoe electrode
on the instrument to identify it.

Stand with both feet onto the foot electrode. If the shoes are dissipative the measurement
starts automatically with a peep signal. After a short measuring time the result is displayed
and the connected gate will open.
OK Green LED flashes The measurement of the footwear in series is o.k.
Hi-Fail Red LED flashes,
audible signal Above the resistance upper limit for series connection
Lo-Fail Rote LED flashes,
audible signal Below the resistance lower limit
(not applicable if lower limit is disabled)
You can step of the foot electrode.
Even if footwear in series is active, you can perform a test according chapter 0 to chapter 0
by pressing a electrode, for example to identify a bad shoe.
In this case the upper limit is 70MΩfor each shoe. Dip switch 3 is without function.

the door opener.
The door opener relay is triggered and stays on for 3 seconds when the test result indicates
OK.
This function must be enabled with DIP switch 8.
