AC Conversion Type:
AC conversions are AC coupled, true rms responding, calibrated to
the rms value of a sine wave input. Accuracies are given for sine
wave at full scale. For distorted signals, add the following crest
factor corrections:
for crest factor of 1.4 to 2.0, add 1.0 % to accuracy
for crest factor of 2,0 to 2,5, add 2,5 % to accuracy
for crest factor of 2,5 to 3,0, add 4,0 % to accuracy
For DCA & ACA:
1. Temperature coefficient: 0.2 x (spec. accuracy)/°C < 20°C or
>26°C
2. Operating temperature: 0...30°C (< 80 % RH); 30...40°C (<75 %
RH)
Maximum Hold:
In the maximum hold function the accuracy is changed as following:
Original accuracy + 10 digits/change steps of range
For example:
At first, the maximum hold reading is 100 mV on 400 mV range. A
voltage vibration changes the maximum hold reading to 120 V. The
change steps of range are 3 steps (400 mV to 4 V to 40 V to 400 V)
so the accuracy is needed to add 3 steps x 10 digital/change steps
of range = 30 digits.
On maximum hold mode the accuracy of resistance is specified
from 400 Ω to 400 kΩ range only.
Auto Power Off
The meter will automatically shut itself off after approximately 30
Minutes after power on.
