2.6 Measurements
2.6.1 Making a Measurement
After adjusting DC Zero:
1. Press the clamp trigger to open the jaws.
2. Clamp the jaws around the conductor to be measured. Use the centering
marks on the jaws to position the clamp around the conductor. If the
measurement is to be used in a power calculation, ensure the arrow on
the clamp jaws (see Figure 1) points in the direction of the current flow:
source load.
3.
Release the trigger, ensuring the jaws are completely and correctly
closed.
4.
Observe the measurement displayed on the measuring instrument.
5.
If the
OL
indicator lights, the current is too high to be measured. If you are
using the MR526 and the sliding switch is set to the
10mV/A
range,
change the setting to
1mV/A
.

2.6.2 Converting to Current
The MR525 and MR526 can both measure current up to 1400A, with 1mV of output
corresponding to 1A. In addition, the MR526 provides a second measurement
range up to 150A, with 10mV corresponding to 1A.
To convert the clamp output to current, divide the voltage reading on the connected
measuring by the V/A coefficient. For example, in the 1400A range a reading of
100mV corresponds to a current of 100A.
