4-1-10. RUN/HOLD Push-buttons
The RUN/HOLD feature on the Model 2300
may be used to simultaneously freeze the
Volts, Amps and Watts displays. This is
accomplished by pressing the button labeled
"RUN/HOLD". A red LED indicates that the
unit is in HOLD mode. A green LED
indicates that the unit is in the RUN mode.
While in the HOLD mode, the button labeled
SAMPLE becomes active. This may be
pressed briefly to update the displays without
leaving the HOLD mode.
Note: Placing the instrument in the HOLD
mode does not affect the overload indicators.
It
is possible to change ranges while in the
HOLD mode however the displays will not be
updated until either the SAMPLE button or
the RUN/HOLD button is pressed. When
using the IEEE-488 option, readings will be
held in the buffer until updated by SAMPLE
or RUN.
