4. Operational guidelines
4.1 Reading hold
During the process of measurement, gently touch the key if you want
to hold readings, and monitor’s display value will be locked.
Touch again the key , the readings hold will be removed.
4.2 Backlight
1. In the process of measurement, if the measurement environment is too
dark, press the key for more than 2 seconds to enable backlight
function. Then about 1 minute later, the backlight function will be
automatically disabled.
2. During this process, press the key for 2 sec. to disable backlight.
4.3 Auto shutdown
1. If no operations occur within 10 minutes after the initialization, the
instrument will be in the state of dormancy. Auto shutdown at this moment
can save power consumption. 2 minutes before shutdown, the buzzer will
sound at an interval of 1 minute.
2. Press any key after auto shutdown to wake the instrument into operation.
3. The function of auto shutdown will be disabled if Hz/NCV key is
pressed while the instrument is initialized.
4.4 Preparation for measurement
1. Press the power key for 2 seconds to initialize the instrument. If the battery
voltage is low (approximately ≤2.4V), the monitor will display the symbol
. At this moment, the battery should be replaced. The instrument will
be shut down if the power key is pressed after the initialization.
2. When the instrument is not used for measurement, it will enter the
automatic scan status and display the diagram below.
4.5 Non contact voltage detection (NCV)
1. Press Hz/NVC key for 2 seconds to enable NCV function. Then the
instrument will display
2. Press NCV key and move NCV sensor closer to the lead line to be
measured. The instrument can detect whether the AC voltage of the
measured lead line is >90V. When the instrument detects AC voltage,
the buzzer will sound alarms while backlight flickers.
