Input impedance of mV range is ≥3GΩ, while others range are about 10MΩ. There will be unstable digital
display in case of mV range open-circuit; after connecting with the load, it can be controlled ≤ ±3 digits.
Maximum input voltage: ±1000V; if the input voltage is ≥1000V, the meter alarms; if it is >1100V, OL symbol
will be displayed on LCD.
10.2 AC Voltage Measurement
Input impedance: about 10MΩ
Display true RMS values. Frequency response: 40~500Hz
Accuracy guaranteed range: 1~100% range, less than 2 digits of residual reading is allowed for short-circuit.
AC peak factor can reach 3.0 at full value (with except for 600V range, which is 1.5 at full value)
Non-sine waveform: Peak factor is 1.0~2.0, accuracy should be added 3.0%
Peak factor is 2.0~2.5, accuracy should be added 5.0%
Peak factor is 2.5~3.0, accuracy should be added 7.0%*
Maximum input voltage: 1000Vrms, if the input voltage is ≥1000V, the meter alarms; if it is >1100V, OL symbol
will be displayed on LCD.

10.3 Resistance Measurement
Overload protection: 1000V-PTC
Range: measured value= displayed value – short-circuit value of test leads
Open-circuit voltage: 0.5V (test current: about 0.4mA)
10.4 Continuity Test Diode Measurement
Range
Resolution Remark
Open circuit voltage: 3.0V (test current: about 1.2mA)
normal voltage of silicon PN junction is about 0.5~0.8V
Circuit breakage resistance value is set as > 50Ω without buzzer beeps
Good conductivity resistance value is set to be ≤10Ω with buzzer beeps
