Commissioning
Remove the protective film from the film keyboard. Open the battery compartment on
the rear of the instrument and, if present, remove the battery circuit breaker strip. The
instrument switches itself on and is immediately ready for operation after inserting the
batteries.
Button (ON/OFF)
The measuring instrument can be switched on and off with this button.
AUTO-OFF function
The instrument switches itself off automatically after approx. 15 minutes if no button
has been pressed during this time.
Button (°C/°F)
This button is provided for switching-over the display between °C and °F. The
currently active temperature units are retained even after switch-off.
Button (HOLD)
The temperature reading currently shown in the display is frozen when the HOLO
button is pressed. When the HOLD button is pressed again, the instrument returns to
measuring mode and shows the actual temperature.
Button (MODE)
When the MODE button is pressed for the first time, the maximum temperature value
appears in the display. The corresponding minimum temperature value is displayed
when this button is pressed again. On the third press of this button the instrument
returns to normal display of the actual temperature values.
To cancel the MAX and MIN values, hold the MODE button pressed for about
3 seconds while in MAX or MIN mode. The display shows --. To show the actual temperature value again, press the MODE button once more.
Display illumination
Press the illumination button. The display is then illuminated for approx 5 seconds.
Thereafter the illumination switches off automatically.
Battery replacement
Replace the batteries when the instrument displays meaningless values on pressing
the buttons.
