1. Slide
ON/OFF
switch to OFF position until unit is intended for use.
2. NOTE that the battery provides power to indicating lights only.
a. The battery does not affect the function of the instrument as a resistance reference.
b. The position lights are provided as a convenience for the operation of the unit during use.
IV. Applications
A. The PAR-809C is a precision resistance reference constructed using 1 percent tolerance resistors to
assure accuracy. It is designed to functionally test the resistance range and performance of a va-
riety of equipment during routine audits, including: in-plant wrist strap checker
PASS/FAIL
range,
footwear checker
PASS/FAIL
range, and other resistance indicating devices.
B. Used in conjunction with the Prostat PRS-812 or PRS-801 Resistance Meters, the PAR-809C func-
tionally tests performance of the Prostat PWA-805 Wrist Strap Auditor. Calibration of resistance
meters is easily confirmed using the PAR-809C.
C. Proper use of the PAR-809C insures accurate, functional performance confirmation of critical ESD
control tools.
V. General Operations
A. Confirming Wrist Strap Tester Resistance Performance Range
1. Plug the two supplied test leads into the PAR-809C receptacles.
2. Plug one PAR-809C test lead into the wrist strap tester’s Wrist strap Ground Cord receptacle.
3. Rotate the PAR-809C’s Position Selector knob to Position 1, the lowest resistance reference.
4. Turn ON the PAR-809c’S position indicating lights by sliding the
ON/OFF
switch located on the
side of the instrument to the ON position.
5. Insure the wrist strap device under test is ON and functional.
6. Using the second PAR-809C test lead with metal alligator clip installed, press the Push to Test
button or plate on the wrist strap tester.
a. The wrist strap tester
PASS
or
REJECT/FAIL
indication should actuate upon contact with the
PAR-809C test lead alligator clip to the wrist strap tester’s push to test button or plate.
b. Note the reference resistance value and the response of the wrist strap device under test.
7. Vary the PAR-809C reference resistance by rotating the Position Selector Knob on the face of
the PAR-809C to the next position and repeat step 6.
