5.3 Measurement specifications

Measurement accuracy
External current sensor input instrument measurement accuracy only
• Values for f.s. depend on measurement ranges.
• “F” in the tables refers to the frequency in kHz.
• To obtain the current or active power accuracy, add the current sensor’s accuracy to
the above current and active power accuracy figures.
• The effective measurement range and frequency characteristics conform to the cur-
rent sensor’s specifications.
• The following input are considered reference values:
Values for voltage, current, and active power for which 0.1 Hz  f < 10 Hz.
Values for voltage and active power in excess of 220 V for which 10 Hz  f < 16 Hz.
Values for voltage and active power in excess of 750 V for which 30 kHz < f  100 kHz.
• When using the CT6841/CT6843, add ±2 mV to the CT6841/CT6843 accuracy after
performing CT6841/CT6843 zero adjustment using the 1 A range noted on the
panel.
Current effective measur-
ing range
±1% to ±150% of the range. However, the effective measurement range depends on
the current sensor’s specifications.
Maximum effective peak
current
The following data reflects the specifications of the instrument alone. In fact, the maxi-
mum effective peak current depends on the current sensor’s specifications.
TYPE.1: ±600% of each current range
TYPE.2: ±600% of each current range
However, the maximum effective peak current is limited to ±400% for the 5 A
range noted on the panel.
Peak exceeded warning If the maximum effective peak current is exceeded, the PEAK OVER I lamp will light up.
