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 rene 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
congured 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 . The next time the MEM button is
pressed, a beep is emitted and the 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 that memory locations are free.
Data is stored as soon as the MEM button is pressed. A long audible signal
conrms the storage.
