Step 2: Connect the second test lead to the 675 Kilohm jack labeled "A" on 41230. Touch the opposite end of test lead to the test plate. Observe the LED's for the proper response as indicated below. Be sure to hold the cord at an insulated point, so that the resistance value is not affected by the body.

Description

The ESD Systems.com model 41230 calibration unit is designed to simplify the process of calibrating wrist strap
and footwear test equipment. The calibration unit allows the user to quickly and easily verify whether a tester is operating within specifica-tions. The 41230 is a passive device,and requires no power source. The calibration unit is manufactured within industry accepted test ranges for both wrist straps and footwear. The wrist strap pass range is set at 750 Kilohm - 10 Megohm, while the footwear test range is set at 750 Kilohm - 100 Megohm. The 41230 is supplied calibrated to NIST traceable standards.

Installation
Remove the calibration unit from the carton and inspect for shipping damage. Each unit should include the following:
1 - Calibration unit, item #41230
2 - 12'' test leads

Calibration Test Procedures

The calibration unit was specifically designed for use in calibration of ESD Systems.com brand test equipment.
The following step by step procedures will cover calibration for specific test units. The procedures will not cover adjustment of the test equipment. For detailed information regarding adjust-ment of specific ESD Systems.com brand testers contact our Customer Service Department at (508) 485-7390.
CALIBRATION OF THE MODEL 41193 WRIST STRAP TESTER
Step 1: Connect one of the test leads to common point banana jack labeled "E" on 41230. Connect the opposite
end of test lead to one of the 41193’s ground jacks located on the front edge of the unit.

Resistance Value Test Output - LED (In Ohms)

Red jack “A” - 675K: Red (Low - hazard) Green jack “B” - 825K: Green (OK - in limits) Green jack “C” - 8.5M: Green (OK - in limits) Yellow jack “D” - 11.5M: Red (High resistance)
Step 3: Repeat the procedure testing across jacks B, C, and D. The different resistance ranges should give the
display shown above. If the tester does not meet calibration specifications,contact factory for adjustment infor- mation, or ask for Tech Brief PS-2055.

CALIBRATION OF THE MODEL 41201, 41202, 41203
WRIST STRAP TESTERS
The models 41201, 41202, and 41203 testers utilize the identical test unit.The difference between the three models is the hardware that is included with each unit. The model 41201 includes only the tester, model 41202 includes the tester and a metal foot plate, while the 41203 is the tester and metal test stand assembly.
This test unit is designed with two separate test circuits with distinct pass fail ranges. The wrist strap test circuit incorporates a 750 Kilohm - 10 Megohm pass range while the footwear test circuit is set to pass at 750 Kilohm - 100 Megohm. Each test circuit needs to be tested individually.For detailed information on these testers ask for Tech Brief PS-2057.

Wrist Strap Test Circuit
Step 1: Connect one of the test leads to common point banana jack labeled “E” on 41230. Connect the opposite end of test lead to the 41201’s wrist cord jack located on the face of the unit.

Step 2: Connect the second test lead to the 675 Kilohm jack labeled “A” on 41230. Touch the opposite end of test lead to the test plate and press down with enough pressure to activate the test circuit. Observe the LED’s for the proper response as indicated below.Be sure to hold the cord at an insulated point, so that the resistance value is not affected by the body.

Resistance Value (In Ohms) Test Output - LED
Red jack “A” - 675K:
Green jack “B” - 825K:
Green jack “C” - 8.5M:
Yellow jack “D” - 11.5M:		 Red (Low - hazard)
Green (OK - in limits)
Green (OK - in limits)
Red (High resistance)

Step 3: Repeat the procedure testing across jacks B, C, and D. The different resistance ranges should give the display shown above. If the tester does not meet calibration specifications, contact factory for calibration, or ask for Tech Brief PS-2057.

Foot Wear Test Circuit

Step 1: Connect one of the test leads to common point banana jack labeled “E” on 41230. Connect the opposite end of test lead to the 41201’s foot plate ground jack located on the side of the unit.

Step 2: Connect the second test lead to the 675 Kilohm jack labeled “A” on 41230. Touch the opposite end of test lead to tester’s test plate and press down with enough pressure to activate the test circuit. Observe the LED’s for
the proper response as indicated below. Be sure to hold the cord at an insulated point, so that the resistance value is not affected by the body.

Resistance Value (In Ohms) Test Output - LED
Red jack “A” - 675K:
Green jack “B” - 825K:
Green jack “C” - 80M:
Yellow jack “D” - 120M:		 Red (Low-hazard)
Green (OK-in limits)
Green (OK-in limits)
Red (High resistance)
