Temperature Measurement - VOLTCRAFT VC891 Operating Instructions Manual

12.4 HOLD function
This function freezes the current reading on the display so that you can record it for
future reference.
When testing live wires, ensure that this function is disabled before
taking any measurements. Otherwise, a false measuring result is
simulated!
Press the "HOLD" button to enable this feature. The multimeter will beep and
"HOLD" will be displayed.
To disable the hold feature, press the "HOLD" button again or change the measure-
ment mode.
12.5 Automatic shut-off function
The multimeter switches off automatically after a preset time if no buttons are
pressed or the control dial is not used. This function saves battery power and ex-
tends the battery life. The time symbol will be displayed at the top left when the
automatic shut-off feature is enabled.
The multimeter will beep one time approx. 1 minute before it turns off. You will hear
a long beep when the multimeter switches off. Pressing any button or moving the
control dial interrupts the shut-off sequence.
To switch the multimeter back on, move the control dial over the "OFF" position or
press the "SELECT" button.
The automatic shut-off feature can be adjusted using the setup function and disa-
bled manually.
12.6 COMP function
The COMP function allows automatic comparison of measurements with preset
limits. Hence, it allows quick evaluation of measurements during time-intensive
measurement series.
12.7 RECORD function
The RECORD function allows mobile recording of measurements via the Blue-
tooth™ interface on the measurement app installed on your smartphone or tablet.
