Volt-Hz. For inputs
from 1% to 5% of range and <50 kHz, add 0.1% of range extra error. For 50 kHz to 100 kHz, add 0.13%.
[4] Specifications are for sine wave input >5% of range. 0.1% errors will be added when the range of input sine wave
is 1% ~ 5%.
[5] 30 seconds OFF after 30 seconds ON is recommend for the continuous current that higher than DC 7 A or AC RMS
7 A.
[6] For frequency<100 Hz.
True RMS AC Voltage
Measurement Method
Measurement Method
AC coupled true RMS measure - up to 1000 V DC bias are permitted on every range
Wave Crest Factor
≤ 3 at full scale
Input Impedance
1 MΩ ± 2% in parallel with <100 pF on all ranges
AC Filter Bandwidth
20 Hz ~ 100 kHz
CMRR (common mode
rejection ratio)
60 dB (For the 1 kΩ imbalance resistance among Lo lead and <60 Hz, maximum ±500
VDC)
True RMS AC Current
Measurement Method
Measurement Method
DC coupled to the fuse and shunt; AC coupled the True RMS measurement (measures the
AC components only)
Wave Crest Factor
≤ 3 at full scale
Maximum Input
The DC + AC current peak value <300% of range. The RMS current including DC current
is <10 A
Shunt Resistor
1 Ω for 20 mA, 200 mA
0.01 Ω for 2 A, 10 A
Input Protection
Rear panel: accessible 10 A, 250 V fast-melt fuse
Internal: 12 A, 250 V slow-melt fuse
Setup Time Attentions
Make sure that the RC return at input terminal has been in a stable state completely (higher than 1 s) before accurate
Make sure that the RC return at input terminal has been in a stable state completely (higher than 1 s) before accurate
measurement;
Input >300 Vrms (or >5 Arms) will cause the self heating of the signal conditioning component to generate error, this
error is included in the characteristics of the instrument. Internal temperature variation results from the self heating
will cause additional an error on ac range that is lower than 0.03% of readings, and it will disappear after a few
minutes

Remarks:
[1] Specifications are for 0.5 hour warm-up.
[2] Except for special marks, the AC input voltage is 15% to 120% of range when <100 kHz and 40% to 120% of
range when >100 kHz. 750 V range is limited to 750 VRMS. 200 mV ranges is for full scale or higher. For inputs
from 30 mV to 200 mV, multiply total % of reading error by 10.
[3] For AC input current from 15% to 120% of range except where noted. 20 mA range specifications are for full scale.
For inputs from 5 mA to 20 mA, multiply total % of reading error by 10. 10 A range is for AC input current from
25% to 100% of range.

Measure Attentions
Generally, errors are leaded into all frequency counters when measuring low voltage or low frequency signal.
