The AC crest factor can be
≤
3.0 at 3000 counts, and can only be
≤
1.5 at
6000 counts. The additional error should be added according to the crest factor
of a non-sinusoidal wave as follows (UT161B/UT161D):
a) Add 4% when crest factor is 1~2
b) Add 5% when crest factor is 2~2.5
c) Add 7% when crest factor is 2.5~3
The AC crest factor can be
≤
2.0 at 10000 counts, and can only be
≤
1 at
22000 counts. The additional error should be added according to the crest
factor of a non-sinusoidal wave as follows (UT161E):
a) Add 4% when crest factor is 1~2

c) Add 7% when crest factor is 2.5~3
Frequency measurement range: 40Hz~500Hz (UT161B), 40Hz~1kHz (UT161D),
40Hz~10kHz (UT161E); input amplitude:
≥
10% of voltage range Duty ratio is
for reference only.
Accuracy guarantee (UT161B/UT161D): 2%~100% of 60mV range, 1%~100%
of other ranges; short circuit allows least significant digit

Max input voltage: 1000V (if the voltage is >1000V, the red indicator light will
be on and the buzzer will sound an alarm; if the voltage is >1010V, the LCD
will display “OL”)
Overload protection: 1000V
