6.2. RECORDING/PLAYBACK OF STORED VALUES (MEM/MR KEY)
6.2.1. PRIMARY MEM FUNCTION (STORAGE)
This function is used to record results in the device's RAM.
These results can be recorded at an address identifi ed by an object number (OBJ) and a test number
(TEST).
An object represents a "box" in which 99 tests can be stored. An object can thus represent a machine
or an installation on which a number of measurements will be performed.
1. When the key is activated, the MEM symbol fl ashes and the small display indicates the next free
OBJ:TEST, for example, 02:01. The main display indicates FrEE.
It is always possible to modify the OBJ:TEST using the
If the user selects an already occupied memory address, OCC appears on the main display.
If a new OBJ is selected, TEST is set to 01.
2. By pressing the MEM key again, the results of the present measurement will be recorded in the
selected memory address (whether occupied or not). The MEM symbol no longer fl ashes and remains
displayed. The time and date of this recording are stored with the data already available (R, U, t).
If the switch is turned before the second press of MEM, the record mode will be exited without
the results being stored.
3. If a programmed-time test was performed, intermediate measurements (samples) are available (see §
4.3). They are automatically recorded under the same OBJ number: TEST as the fi nal measurement.
Memory space available
This function is automatically activated when recording a result.
Press once on MEM to obtain the next free OBJ:TEST; the indication of the bargraph is proportional to
the free memory available.
 If the entire memory is free, all the segments are activated.
If the entire memory is full, the left-hand bargraph arrow fl ashes.

When the recording is completed, the bargraph disappears.

6.2.2. SECONDARY MR FUNCTION
The MR function is used to recall data from the memory.
 When the key is activated, the MR symbol is displayed (not fl ashing).
The small display indicates the last occupied OBJ:TEST, for example, 02:11.
"11" above the TEST symbol is fl ashing, the normal modifi cation procedure with keys
must be used to select the desired OBJ:TEST.
If a new OBJ is selected, TEST is automatically set to the largest stored number.
The values at the address selected by OBJ:TEST are shown in the main display. Additional results
can be viewed using the R-DAR-PI-DD key.
 The V-TIME key is active and gives access to date, time, voltage, duration and OBJ:TEST number
of each stored measurement. If the recording selected by the OBJ:TEST number corresponds to
