: 10 V, 100 V or 500 V.
Connection
Note
Checking Measurement Cables Before Measurements
Before performing resistance measurement, the test
probes on the measurement cables should be short-cir-
cuited in order to assure that the instrument displays a
value of less than 1 k
(see section entitled “Measuring
Resistance –
Function”). In this way, incorrect connec-
tion can be avoided and broken measurement cables
can be detected.
➭
Connect the device under test to the
+
and
COM
jacks.
Wiring examples for the ESD measurement are included in sec-
tions 7.1 through 7.5.
Resistance can only be measured at voltage-free objects. If mains
voltage or interference voltage is applied to the measurement
inputs, measurement cannot be started.
Set Parameters
All of the following parameters are used only for measurement
documentation in the device’s internal database, and do not influ-
ence the measurement itself. Database functions are explained in
sectionl 10.
Verification – Qualification
Parameter
You can specify whether
the measurement in
question involves a veri-
fication or a qualification
for documentation of
your measurement in the
device’s internal data-
base.
The respective selection
is displayed in the key in
the start menu.
DUT Parameter
You can selected a suit-
able device under test
from a list for documen-
tation of your measure-
ment.
Measuring Point Param-
eter
You can specify a maxi-
mum number of different
measuring points from
001 to 099 for docu-
mentation of your mea-
surement.
The specified measur-
ing points can be
directly selected with the
AUTO key (see “Fast
Pole Switching” on next
page).
Limit Value > Limit
Parameter
The lower limit value
selected here appears to
the left above Resd.
The red LED lights up if
the limit value is fallen
short of.
Limit Value < Limit
Parameter
The upper limit value
selected here appears to
the right above Resd.
The red LED lights up if
the limit value is
exceeded.
