34 Clamp-on Ground Resistance Tester Model 6416
CURRENT GREATER THAN 40 A
If the current is greater than 40 A:
■
The current display indicates O.R
(Over Range).
Figure 6-9
6.2 ROTARY POSITION (A)
In the A position, the clamp measures the electrical current, independently of any
ground/earth measurement.
If desired, configure the current alarm threshold as desired (see §4.4, menu #6).
6.2.1 Making a Measurement
■
Turn the rotary switch to the A position, and wait several seconds while the
instrument performs internal calibration.
■
Clamp around the conductor to be measured. If the clamp is incorrectly closed,
the icon is displayed.
■
If necessary, use the HOLD button to freeze the measurement.
■
If necessary, use the MEM button to store the measurement.
Once the measurement has stabilized, the display will indicate the value of the
current flowing in the conductor.
NOTE:
If the preset alarm threshold
is exceeded, the threshold set
value and the value of the current
measured blink.

6.3 ROTARY POSITION - (MR)
The MR position (Memory Recall) is used to display measurements previously
stored when the MEM button was pressed.
6.3.1 Displaying Stored Measurements
■
Set the function switch to the MR position.
■
The type of data that is displayed is dependent on whether Standard or
Advanced mode was selected during SET-UP (see § 4.4, menu #9).Data
