Wrist strip /Foot-grounding test device
Calibration
procedure:
The
resistance test by W/S tester must be over 740K次(working
resistance as 750K次-10.5M次), however, highest resistance
must be less than 11M次, and resistance tested in shoe cover
must be over 740K次( working resistance is 750K次-35M次), however
it must be less than 40M次, and resistance tolerance is 20%.

It shall
be recommended to recalibrate the measurement instrument once
a year from calibration time last time.
Instruction:
MAXCLEAN
M-FWS-1 tester can be touchable and used as 3 status, which
is ideal for fast and multiple test for ESD grounding device.
This tester shall be used as one of calibration instruments
according to the calibration standard inclusive of daily inspection
of technical requirement and program described as 6.1.3.2
in ANSI ESD S20.20. Combo tester integrated with design for
unique dual-testing circuit, which not only improve test speed,
but also does not need any single wrist strip/foot panel tester.
Furthermore, FWS-1 configures with 750K次-10M次 circuit used
to test wrist strip and 750K次-35M次 circuit used to test shoe
cover, FWS-1tester is ideal for testing of wrist strip and
shoe cover. Test parameter has been preset in factory, however
it can be used only after one needed by you coordinates with
test parameter. Here FWS-1 tester is easily operable, green
indicator stands for normal operation status, red one and
sound for higher or lower resistance

Test
for wrist strip
Test
can be used to calibrate if there is switched on among
operator, wrist strip and grounding lead, see diagram
I.
A. Plug end shall be put into frontal socket of tester
when wrist strip is worn.
B. Switch shall be turned on WRIST CORD.
C. Tester shall be operated after 2-3s if its button
is pushed on. Notes: metal part must not be touched
by mistake when testing.
D. If green indicator "Normal PASS"LED turns on, it
shall indicate normal operation between wrist strip
and grounding lead.
E, If "FAIL LO"or"FAIL HI"LED turns on and alarms, inspection
shall be done.
