Battery Test
symbol is displayed automatically if battery voltage
drops to below approximately 2.3 V.
Battery Saving Circuit
The instrument is switched off automatically if the measured value remains
unchanged for a period of approximately 10 minutes, and if none of the control
elements are operated during this period. Automatic shutdown can be disabled.
