[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 ACV, 3 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
ACV 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), 20/s (200 Hz). Additional errors will Not occur for the
frequency greater than the filter settings.
[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.
