KEYBOARD
AND
MENU
DESCRIPTION
Foreword
The instrument keyboard is composed of single-function keys, like the MENU key, and double-
function keys such as the ON-OFF/Auto-OFF key.
In the double-keys, the function in the upper part is the "main function", while the one in the bottom
part is the "secondary function". When the instrument is in standard measurement mode, the main
function is active. In the menu or in conjunction with the FUNC key, the secondary function is
enabled.
The pressing of a key is accompanied by a short confirmation beep: a longer beep sounds if the
wrong key is pressed.
Each key specific function is described in detail below.
ON-OFF/Auto-OFF key
The instrument is turned on and off using the ON/OFF key. The turning on enables all display
segments for a few seconds, starts an auto-test including the detection of the probe connected to the
input and sets the instrument ready for normal measurement.

During turning on, should no probes be connected, the message "NO_PRBE_ SER_NUM" is
displayed in the line for symbols for a few seconds, and in the main line a series of dashes
appears while the ERR message replaces the temperature.
When the probe is inserted into a functioning instrument, the "NEW_PROB_DET" (New
probe detected) message appears: as the probe's data are captured upon turning the
instrument on, it is necessary to turn the instrument off and on again.
Replace the probes when the instrument is off.

Automatic turning off
The instrument has an
AutoPowerOff
function that automatically turns the instrument off after about
8 minutes if no key is pressed during the intervening time. The
AutoPowerOff
function can be
disabled by holding the HOLD key pressed down when turning the instrument on: the battery
symbol will blink to remind the user that the instrument can only be turned off by pressing the
<ON/OFF> key.
