To avoid false reading, replace the battery if the battery low power symbol
Also pay special attention to the warning sign
the tested voltage or current must not exceed the values listed on the meter.
The Meter automatically shuts down if there is no operation for 15 minutes. You can
wake up the Meter by pressing any key. To disable auto shutdown, switch the dial to OFF
position, long press HOLD key and turn on the meter.
1. AC/DC voltage measurement (see picture B)
1.1 Switch the dial to "V~" for AC-voltage or into "V " for DC-voltage.
1.2 Insert the black test lead into the COM jack, the red test lead into the "VΩmA" jack.
Connect test leads with the load in parallel.
Note:
• Do not measure voltage over 250 Vrms, or it may expose users to electric shock and
damage the Meter. If the range of the voltage to be measured is unknown, select the
maximum range and reduce accordingly.
• Please pay extra attention when measuring high voltage in order to avoid electric
shock.
• Before using the Meter, it is suggested to measure a known voltage for verification.
2. Temperature measurement (see picture D)
2.1 Switch the dial to temperature test.
2.2 Insert K-thermocouple into the Meter and fix the temperature probe to the measured
object. Read the value when it is stable.
Note:
• Only K-thermocouple is applicable. The measured temperature should be less than
250°C / 482°F.
Input voltage ≥ 250 V (AC/DC), buzzer will continuously beep Indicating measure
range is at limit.
Input current > 10 A (AC/DC), buzzer will continuously beep indicating measure range
is at limit.
• 1 min before auto shutdown, 5 continuous beeps.
Before shutdown, 1 long beep.
• Low power warnings:
Voltage of the battery < 2.5 V,
