6.2 RECABLEING / PLAYBACK OF STORED VALUES (MEM/ MR KEY)
6.2.1 MEM PRIMARY FUNCTION (STORAGE)
This function is used to recable the results in the instrument's RAM.
The results can be stored at addresses identified 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 are performed.
1. When the MEM key is activated, the following screen is displayed.
If the user selects a memory address that is already
occupied, this screen is displayed and prompts the
user to confirm or cancel erasure of the content of
the address.
To validate, use the 4key.
2. When the MEM key is pressed again, the results of measurements in progress are recorded at the
selected memory address (whether occupied or not).
All information about a measurement will be stored at a single location in memory: date, time, test mode and
voltage, insulation resistance, capacitance, residual current, and, possibly, DAR, PI, DD, measurement
referred to the reference temperature, or even the R(t) graph.
Note: If a key other than MEM or the switch is activated before MEM is presses a second time, the
recable mode is exited without the results being stored.

The flashing cursor idetifies the first free Obj : Test
location, here :
13 : 59
(the Obj. number is that of the last measurement stored,
but the Test number is incremented by 1).
It is always possible to modify Obj. : Test using the
4,3,5 and 6keys.
If a new Obj. is selected, Test is set to 01.
