5.0 SWITCHING ON AND OFF
5.1 Display Test
The ‘ON/OFF’ button on the keypad switches on the
instrument. When the instrument is first switched on the unit
performs a self-test and the whole display will be energised.
After a short pause the display will revert to normal
temperature display. The current time is also displayed.
5.2 Auto Power off (APO)/Power Saving
The N9002 can be set to auto-power-off three minutes after
the last button operation or to remain permanently on until
manually switched off. This mode is indicated on the LCD in
the lower portion of the display by the word AUTO. Enabling
or disabling auto-power-off (APO) is available from the
keypad in SETUP.

6.1 Display Hold
Pressing ENTER/HOLD will prevent display updates for
actual temperature displays and suppresses update of max
and min values. HOLD will appear on the display to indicate
this mode. Pressing ENTER/HOLD again will cancel display
hold.
6.2 Maximum & Minimum Mode
The N9002 instrument automatically updates the maximum
and minimum readings as soon as the instrument is
switched on. These can be displayed by pressing the MAX
or MIN buttons. If both channels, T1 and T2, are enabled,
MAX or MIN is displayed for both channels. If T1 or T2 only
is enabled both MAX and MIN are displayed together for
the enabled channel. MAX and MIN readings can be reset
individually at any time for all channels by pressing CLEAR
followed by either MAX or MIN.
