ABOUT THE PRODUCT
ӹTester for checking personal grounding before entering an ESD protected area
(EPA)
ӹTesting footwear system and wrist strap/groundable ESD smock system at the
same time
ӹCan be used to test a groundable ESD smock system
ӹTest result indication on LCD display, with LED light and sound
ӹSelectable test modes: Footwear sytem test only, or footwear system and wrist
strap/groundable ESD smock system combined test
ӹFor indoor use only
The AIJGO-22LCD is an easy-to-use tester for checking personal grounding before
entering an ESD protected area (EPA). High load-bearing construction, it may be a
good choice if speed and security are important factors due to the large number of
entrances. Tester with LIGHT BAR system – such AIJGO products have a steel touch
button, the measured results are indicated by LED lights. The type of test can be
changed according to the entrance regulations: only footwear system test or the
combined test of the footwear system and wrist strap/groundable ESD smock
system. Thanks to the dual foot electrode, the tester simultaneously measures the
resistance of the right and left foot relative to the hand. After the test, the measured
values are displayed on the built-in LCD display. The tester can be connected to a
gate using the relay output (e.g. to a turnstile entrance gate, swing gate, etc.). It can
be installed on an entrance gate, table, wall or stand.
The tester is supplied with manufacturer’s calibration certicate, dual foot electrode,
mounting plate and universal holder.
CE declaration
We declare that the AIJGO-22LCD product complies with the requirements of IEC
61340-5-1, ANSI/ESD S20.20 and Directive 2001/95/EC (General product safety).

Resistance values indicated as acceptable by the tester
Default setting when measuring footwear system 100 KΩ – 35 MΩ
An upper value of 100 MΩ can be set using the red switch at the bottom of the tester. However, after setting a dierent
limit from the one used previously, the device must be restarted for the change to take eect.
Default setting when measuring wrist strap/
groundable ESD smock system 750 KΩ – 35 MΩ

ASSEMBLY INSTRUCTIONS
Stand version
1.
Retool the red switch on the bottom of the
tester to the desired position, if necessary, to
set the measurement resistance limit of the
footwear system.
