Operation, Installation and Calibration Instructions
N.I.S.T. Calibration Unit for Wrist Strap and Footwear Testers
Figure 1. 07010 Calibration Unit
Description
The Desco model 07010 calibration unit is designed to
simplify the process of calibrating wrist strap and foot
ground test equipment. The calibration unit allows the
user to quickly and easily verify whether a tester is
operating within specifications. This product can be
used as one of the tools to fulfill the ANSI/ESD S20.20
paragraph 6.1.3.2 “Compliance Verification Plan”.
Verification should include routine checks of the
Technical Requirements of the Plan. Per Table 1, the
technical requirement test method for “Continuous
Monitors” is to be “per the manufacturer specifications”.
The 07010 is a passive device, and requires no power
source. The calibration unit is manufactured within
industry accepted test ranges for both wrist straps and
foot grounders. The wrist strap pass range is set at
750K - 10M, while the foot ground test range is set at
750K - 100M. The 07010 is supplied calibrated to
NIST traceable standards.
The 07010 Calibration Unit is an important tool for
optimization of an ESD control program. A leading
corporation estimates a $95 to 1 return on every dollar
invested in ESD control. However, the ESD protective
products utilized must be working, so it is essential that
testers are in calibration that are used to verify the
parameters of wrist straps and foot grounders. The
07010 Calibration Unit easily pays for itself. Instead of
returning to Desco, a Calibration House, or even your
Metrology Department, testers can be NIST calibrated
where located in the factory being out-of-service only a
couple minutes. No need to have an extra replacement

CALIBRATION OF THE MODEL 98280
WRIST STRAP TESTER
Step 1: Connect one of the test leads to common point
banana jack labeled "E" on 07010. Connect the
opposite end of test lead to 98280 tester's wrist strap
jack located on the front of the unit and switch the
selector switch to “WRIST STRAP”.

98280.
Step 2: Connect the second test lead to the 675K jack
labeled "A" on the 07010. Touch the opposite end of
test lead to touch tester plate and press down on tester
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.
