Automatic Switch-Off - TESTBOY TB 65 Bedienungsanleitung

Operation

Automatic switch-off

After 15 minutes in the switched on condition, the instrument
automatically reverts to the sleep mode, in order to save battery
capacity. Hereby, the display is switched off and only very little
energy is consumed.
In order to revert to normal operating mode, press the button
"POWER" twice.
Automatic background lighting
For measuring in a dark environment, the background lighting of the
display is automatically switched on by the light sensor (9).
As soon as reverting to a brighter area, the lighting is switched off.
Saving function (HOLD)
At difficult measurement positions, the display cannot perhaps be
read correctly.
By pressing the button "HOLD", the actual measurement value is
frozen and can then be read in comfort.
By pressing again, you revert to normal measuring mode.
