Prostat PAR-809C - Applications of the PAR-809 C; Testing ESD Control Equipment; Use with Prostat Meters and Auditors; General Operations and Testing Procedures

1. Slide  switch to OFF posion unl unit is intended for use.
2. NOTE that the baery provides power to indicang lights only.
a. The baery does not aect the funcon of the instrument as a resistance reference.
b. The posion lights are provided as a convenience for the operaon of the unit during use.

A. The PAR-809C is a precision resistance reference constructed using 1 percent tolerance resistors to
assure accuracy. It is designed to funconally test the resistance range and performance of a va-
riety of equipment during roune audits, including: in-plant wrist strap checker  range,
footwear checker  range, and other resistance indicang devices.
B. Used in conjuncon with the Prostat PRS-812 or PRS-801 Resistance Meters, the PAR-809C func-
onally tests performance of the Prostat PWA-805 Wrist Strap Auditor. Calibraon of resistance
meters is easily conrmed using the PAR-809C.
C. Proper use of the PAR-809C insures accurate, funconal performance conrmaon of crical ESD
control tools.

A. Conrming 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 Posion Selector knob to Posion 1, the lowest resistance reference.
4. Turn ON the PAR-809c’S posion indicang lights by sliding the  switch located on the
side of the instrument to the ON posion.
5. Insure the wrist strap device under test is ON and funconal.
6. Using the second PAR-809C test lead with metal alligator clip installed, press the Push to Test
buon or plate on the wrist strap tester.
a. The wrist strap tester PASS or  indicaon should actuate upon contact with the
PAR-809C test lead alligator clip to the wrist strap tester’s push to test buon 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 rotang the Posion Selector Knob on the face of
the PAR-809C to the next posion and repeat step 6.
