Clamp-on Ground Resistance Tester Model 6416
5.5 TURNING THE INSTRUMENT OFF
The instrument can be turned OFF in two ways:
■
Manually:
Turn the rotary switch to OFF.
■
Auto Power OFF:
This function activates after 5 minutes of no activity (no
button press, no change of switch setting, and no opening of the jaws).
- Fifteen seconds before Auto Power OFF, a short audible signal is emitted
and the display blinks once a second.
Auto Power OFF can be disabled in SET-UP (see § 4.4, menu #3). The
symbol is then displayed.
5.6 STANDARD AND ADVANCED MODES
The instrument has two modes.
■
Standard Mode:
Makes the standard loop resistance and leakage current
measurements.
■
Advanced Mode:
Used to refine and complete the measurements:
- Impedance at the selected frequency.
- Contact voltage.
- Resistive and inductive components of the loop impedance.
The choice of Standard or Advanced mode and the alarm thresholds are
configured in
SET-UP
(see § 4.4, menu #9).
5.7 MEMORY
5.7.1
Memory Capacity
The Model 6416 can store up to 300 measurements. When its memory is full,
the sequence number is replaced by
FULL
. The next time the MEM button is
pressed, a beep is emitted and the
FULL
indication blinks. You will need to erase
the entire memory before recording again (see § 4.4, menu #1).
5.7.2
Storing Measurements into Memory
The values displayed during the measurements can be stored in memory and
read later.
Storage of the data is available in both the Ω+A and A measurement modes,
provided the memory locations are free.
Data is stored as soon as the MEM button is pressed. A long audible signal
confirms the storage.
