Measurement is made with a 10 mA dc current and is highly resistant to ac
currents flowing between the measurement points as a result of chassis leakage
current from either or both devices. However, such leakage current may have a
dc component from rectification within the instrument. This dc current adds
and subtracts from the measurement current, resulting in some error that can be
corrected for by reversing the connections, remeasuring, and averaging the two
readings.
To measure resistance between two points:
1. Connect the two black chassis cables with clamps with black insulation to
the CHASSIS and EXTERNAL connectors on the top panel of the
Analyzer.
2. Clip the cables onto the two points to be measured.
Note
Do not plug a device into the Analyzer. Ensure that ground
connections do not provide parallel measurement circuits causing
erroneous results.
3. Set the FUNCTION switch to EARTH RESISTANCE .
