[1]. AC Specification: It will be available after 60 minutes of warm-up, sine
wave as well as 1/s speed rate.
[2]. The entire range of measurement will pass the set range by 20% except
the tests of 750 VAC, 3 A AC and 10 A AC.
[3]. Specifications are for sinewave input >5% of range. For inputs from 1%
to 5% of range and <50 kHz, add 0.1% of range additional error. For 50
kHz to 100 kHz, add 0.13% of range. The measurement range of 750
VAC is limited within the range of 7.5 x 10
^
7 Volt–Hz.
[4]. Three speed settings provided for low-frequency performance: 1/s (3
Hz), 5/s (20 Hz), 50/s (200 Hz).
[5]. Specifications are for sinewave input >5% of range, and is beyond 10 μA AC.
For inputs from 1% to 5% of range, add 0.1% of range additional error.
[6]. The 10A range of measurement is available for the terminals on front
panel only. Due to power factor resulting in temperature rise, 2 mA
increment per one ampere when input is greater than 5 A rms.
[7]. Accuracy below 10 Hz is a supplementary value.
[8]. Accuracy below 50 Hz and above 1 kHz at above 200 Vrms are
supplementary value. Accuracy above 70 Vrms at above 100 kHz are
supplementary value.
[9]. Accuracy below 10 Hz and above 5 kHz are supplementary value.
Accuracy above 0.2 Arms at 10 Hz to 20 Hz, above 3 A at 20 Hz to 45
Hz, and above 1 A at 1 kHz to 5 kHz are supplementary value.
Accuracy below 40 Hz and above 1 kHz at 100 µA range are
supplementary value.
