key is difficult. If necessary, then press the
HOLD
key to freeze the device and
release the handle.
If the
HOLD
key is not pressed, closing the clamp automatically causes an exit
from the
Pre-hold
mode.
4.8 STORAGE OF THE DATA
The values displayed during the measurements can be stored and read out later.
4.8.1
CONDITIONS
Storage of the data is available in both the
Ω+A
and
A
measurement modes,
provided that memory locations are free.
4.8.2
EFFECTIVE STORAGE
The data are stored as soon as the
MEM
key is pressed. A long audible signal
confirms the storage.
4.8.3
INFORMATION CONCERNING THE STORED DATA
All calculated impedance and/or current values, together with the values
accessible in the secondary screens in the
Advanced
, mode, are stored as soon
as the
MEM
key is pressed, namely:
■
Current measurement (A);
■
Measurement of the resistance, inductance, and impedance (Z);
■
Contact voltage measurement (V);
■
Present configuration of the clamp;
■
Sequence number of the record;
■
Time and date of the record.
The display unit indicates the sequence number of the last measurement
recorded, or
0
if the memory is empty. The data are preserved when the device is
off or without a battery.
4.8.4
MEMORY FULL
When 300 values have been stored and the memory is full (model C.A 6416), the
sequence number is replaced by
FULL
. The next time the
MEM
, key is pressed, a
disablement beep is emitted and the
FULL
indication blinks. Storage is rejected; it
is then necessary to erase the whole memory before recording again. Refer to
chapter 8, menu 1.
The communicating model C.A 6417 has a larger recording capacity, 2000
measurements. The PC interface can be used to activate a circular recording
mode in which the 2000 most recent values are kept, with a maximum sequence
number of 9999. If the circular recording mode is activated, as soon as the
threshold of 2000 values is exceeded, the sequence number is displayed
alternately with
FULL
in order to report the overwriting of the oldest records. When
the threshold of 9999 records is reached, the sequence number is replaced by
