8.5 Resetting
Procedure
The
personal
DataRAM memory can be reset through commands entered on its own
keypad (i.e. without requiring a PC).
Resetting accomplishes the following:
•
Erases all stored data from memory;
•
Resets all parameters and operating conditions to their default values and
conditions; and
•
Cancels the zero correction offset.
WARNING: THE RESET TEST WILL ERASE ALL DATA STORED IN
MEMORY AND SET ALL PARAMETERS TO FACTORY
DEFAULT SETTINGS. DOWNLOAD ANY DATA BEFORE
THE RESET PROCEDURE.
The procedure to reset the instrument is as follows:
Starting with the unit shut off, press the
EXIT
and
ENTER
keys at the same time,
and while holding down those two keys, press
ON/OFF
. The screen will then
indicate:
PDR SELF-TEST...
and several diagnostic screens will appear in rapid sequence (see Section 16.0,
Resetting/Electronics Checking Mode), ending in the message TESTING
COMPLETE. The unit will shut off. When turned on again, the
personal
DataRAM
memory will have been reset, as described above.
The
default
values and operating conditions of the
personal
DataRAM are:
•
Logging period (LOG INTRVL): 60 seconds
•
Logging status: disabled (LOGGING DISABLED)
