OPERATING INSTRUCTIONS
• Turn off the Instrument before connecting or
• Do not use this Instrument with any accessories not
• Do not use this Instrument to measure live circuits.
• The test weights included in this kit are heavy. Exercise
NOTE: The following procedures should be followed each time
the Model 701 is used.
BATTERY TEST
Place the Instrument on a table top or other stable surface.
Set the main selector switch to BATTERY TEST. Press
TEST and hold for 15 seconds. The pointer should come to
rest in the green area of the BATTERY scale. If the pointer
is in the red area to the left of 100V, replace the battery and
retest. If the pointer is in the red area to the right of 100V,
the Instrument may need recalibration.
CONTINUITY TEST
Place the Instrument on a table top or other stable surface
and attach the leads as shown in Figure 4-1. Place the test
weights on the calibration plate or other bare metal surface
and plug in the test leads. Set the main selector switch to
CONTINUITY TEST. Press TEST. The pointer should
come to rest in the green section of the CONTINUITY
scale. If not, the test leads may be defective or the weights
may require maintenance or cleaning.
SURFACE TEST (Resistance Measurement)
Refer to the immediate two following sections to determine
which measurement(s) should be used for your application.

and attach the leads as shown in the appropriate sketch
figures 5-1 through 5-5. Set the Main Selector Switch to the
desired SURFACE TEST voltage. Place the test weight(s)
on the surface to be tested and connect the test leads. Press
TEST for 15 seconds and then read the resistance from the
OHMS scale. After all readings have been completed, return
the Main Selector Switch to the OFF position.
RESISTIVE CHARACTERIZATION OF
STATIC CONTROL WORK
SURFACES
GENERAL
This section provides a summary of the types of surface
measurements specified and described by ESD-S4.1.
Measurements are performed for three reasons:
1. Periodic performance testing of installed static control
2. Qualification of installed static control work surfaces.
3. Evaluation of static control work surface materials.
NOTE: The following paragraphs are offered as a condensed
summary of the test methods and procedures outlined in the
EOS/ESD standard. For complete details, refer to the standard.

work surfaces.
OF INSTALLED STATIC CONTROL SURFACES
(Measurement of resistance from the top of an installed
surface to ESD GROUND (R
temperature and humidity): Note: ESD GROUND is the
point at which the ground cord or other grounding
conductor from the static control surface is connected to.
The ground point may be an electrical ground, building
ground, or other suitable ground. If you have questions
concerning the correct ground, refer to EOS/ESD
STANDARD S6.0 and/or contact a qualified electrician.
This Resistance-to-Ground test is the most important test
that can be done on a static control surface because it
verifies that the surface is working correctly and will
