Spec

■ ELECTRICAL SPECIFICATIONS:

Acceracy is given as ±(% of reading + counts of least significant digit) at 23°C ±5°C, with

relative humidity Less than 80% R.H. ACV and AC μA/ mA/ A specifications are ac coupled.

ture R.M.S. and are valid from 5 % of range to 100 % of range. The crest factor may be up to

3.0 at full-scale except the 1000 V ranges where it is 1.5 at full scale. For non-sinusoidal

waveforms, add (2% reading + 2% full scale) typical, for crest factors up to 3

□ DC Voltage

□ AC Voltage

Notes:

1. Overload Protection: 1000V R.M.S.

2. Input Impedance: 10MΩ (norminal) in parallel with <100pF

3. For signal less than 10% range, additional 5 counts to specify accuracy.

□ HARMONICS RATIO

Harmonics Ratio function generates a value from 0% to 100% to indicate the deviation

between non-sinusoidal and a sinusoidal waveform, which is a good indication of the pressence

of harmonics. Pure sinusoidal waveforms without hamonics have a Hamonics Ratio of 0%

The higher Harmonics Ratio, the more hamonics are present

□ CAPACITANCE

• The accuracy is based on film capacitor or better and use Relative mode for residual value.

□ DIODE CHECK/ AUDIBLE CONTINUITY TEST

Notes:

1. Overload protection: 600V R.M.S.

2. Builit-in buzzer sounds when reading is below 50 mV approx. and single

   tone for normal forward-biased diode or semiconductor junction as 0.3V≤ Reading ≤0.8V.

 □ RESISTANCE

Notes:

1. Maximum open voltage:<+3.5V

2. Instant Continuity:Built-in buzzer sounds when resistance is less than 10.0Ω

3. The accuracy of 1000Ω and 10kΩ is specified after Relative function,

    which is used to substrate the test lead resistance and the themal effect.

4. For the range of 100MΩ the RH is specified for <60%.

□ DC CURRENT

□ AC CURRENT

□ TEMPERATURE TEST

Notes:

1. The accuracy does not include the tolerance of themocouple probe, and the meter should

    be putting on the place will be operating for 1 hour at least.

2. Do not allow the temperature sensor to contact a surface that is eneraized above 33V

   RMS or 70V DC. Such voltages will pose a shock hazard.

3. The temperature calculation is acording to the standard of NIST175 and

    EN/IEC-60548-1.

□ FREQUENCY

•  Overload protection : 1000V; <20,000,000VxHz
