Auto-Off
Enables the automatic shut-off feature for the instrument. If
ON, the instrument will automatically shut-off in 60 minutes
after no keys are pressed to save power. If OFF, the meter
will stay powered continuously until either the internal power
switch on the battery board is turned OFF, or the battery
voltage drops to the cut-off point (approximately 30 days on
a two C-cell alkaline batteries). Press ENTER to initiate user
entry mode, and the entire value will flash. Use the UP
arrow key to modify the desired display value. The choices
are
OFF
and
ON
. Press ENTER to store the new value
BackLight
The Back-light screen is used to set the operating conditions
under which the backlight will turn on. The default is AUTO,
which configures the light to come on whenever any key is
pressed. The light will automatically shut off if no key is
pressed for 30 seconds. Other selections are OFF (always
off), AL for Alarm, where the light comes on in alarm
condition and flashes under a Fail condition, and ON (always
on). Do not select ON when using internal batteries for
operation, as battery life will be greatly reduced.
Set Default
The Set Default function allows the user to return the
instrument back to factory default data for all user settings or
for just the calibration default. It is intended to be used as a
last resort troubleshooting procedure. All user settings or
the calibration settings are returned to the original factory
values. Hidden factory calibration data remains unchanged.
Press ENTER to initiate user entry mode and select either
CAL
or
ALL
with the UP arrow key. The default CAL routine
will reset the zero offset to 0.0 nA and reset the slope to
100%. The default ALL routine will reset all program
variables to factory default and should be used with care
since it will change any user settings that were programmed
in the field.
