The following sections describe the types of measurements and the different
possible selections and screens which are available using the DISPLAY button,
depending on the configuration and the State (1, 2 or 3) of the instrument.
4.4 Bond Resistance/Continuity Measurement
The instrument is designed to measure resistances up to 100kW. The DC mea-
surement is at 16V and the test current is ≥ 200mA up to 20W (complies to IEC
standard 61557-4) and less above 20W. This function is used to measure bonding
resistance and/or continuity of grounds and bonds.
There are two set-ups:
•
2-Pole or 2-Wire measurement:
terminals E (X) and H (Z) are used. The test lead resistance may be manu-
ally removed.
•
4-Pole or 4-Wire measurement:
Sensing method. It uses 4 test leads and the test lead resistance is
automatically "eliminated" from the measurement. Users concerned by the
lead resistance (and don't want it in the measurement) use this method. All
four terminals are used.

Configuration Settings
By default, the instrument is in MANUAL mode and will perform a 2-Pole measure-
ment.
To change the configuration before making the measurement, use the Hz
and ► buttons to:
•
Select the measurement mode (

Select the number of wires for the measurement (2- or 4-Wire).
MANUAL mode, select the measurement current polarity.
