Digital Multimeter User Manual
QM1571
Thank you for purchasing this Wireless Data Logging Digital Multimeter. The
wireless communication function of this multimeter allows you to transmit
data wirelessly from the multimeter to your PC. This allows accurate recording
at a much faster and detailed rate than manually writing down numbers.
The true RMS function ensures accurate readings, regardless of load type or
current wave shape. Packed with plenty of features, this multimeter will be
your constant companion on-site, given its tough double moulded body and
IP67 rating.
Please familiarise yourself with the functions of the multimeter before use.
We recommend retaining this manual for ease of reference.
• Improper use of this meter can cause damage, shock, injury or death.
• Always remove the test leads before replacing the battery or fuses.
• Before using the meter, please inspect the condition of the test leads and
the meter itself for any damage. If damage is present, please discontinue

• Do not measure voltage if the voltage on the terminals exceeds 1000V above
earth ground.
• Use great care if voltages are greater than 30VAC RMS. Anything above this
is considered a shock hazard.
• Always discharge capacitors and disconnect power before performing diode,
resistance or continuity tests.
• Do not exceed the maximum limits of the input values shown in the
