Overview This Operating Manual covers information on safety and cautions. Please read the relevant information carefully and observe all the Warnings and Notes strictly. Warning To avoid electric shock or personal injury, read the “Safety Information” and “Rules for Safe Operation” carefully before using the Meter.
In the event you find any missing or damage, please contact your dealer immediately. Safety Information This Meter complies with the standards IEC61010: in pollution degree 2, overvoltage category (CAT. III 600V,CAT IV 300V) and double insulation. CAT. III: Distribution level, fixed installation, with smaller transient overvoltages than CAT.

Warning: To avoid false readings, which could lead to possible electric shock or personal injury, replace the battery as soon as the battery indicator appears.
Measurement Operation Preparation ● 。 Turn on Rotary Switch ●Replace the battery as soon as the battery indicator “ ” appears on the display. A. AC Voltage (main display) + Frequency (secondary display) Measurement (see figure 4) figure 4 The AC Voltage ranges are:15V, 100V, 300V and 600V The frequency range is:20Hz~100Hz To measure AC voltage + frequency, connect the Meter as follows:...
1. Insert the red test lead into the V A terminal, blue test lead into the V B terminal, yellow test lead to V C input terminal and black test lead to the COM input terminal. 2. Connect the red test leads (VA input terminal), blue test leads (VB input terminal) and yellow test leads (VC input terminal) to the corresponding three phases loaded live wire.
otherwise it will cause deviation. The Meter can only measure one conductor at a time, to measure more than one conductor at a time will cause deviation. 4. The double display shows the AC current True RMS value and AC voltage True RMS value.
