14.3 Auto-ranging
Auto-ranging function is available at W, Wh, DEMAND and WAVE Ranges. Current values in wide range
can be measured with this function; it is helpful when load capacitances vary dramatically according to
day and time.
● Range : 2-range-auto/ max and min range of each Clamp sensor
● Range shift to upper one when crest values equal to twice as much as F.S (sine wave) at min range
is
detected.
Accurate values may not be obtained when substantial fluctuations in 1 sec.
14.4 Operation at AC power interruption
When an AC power supply is interrupted during recording, KEW6310 operates as follows.
● Power supply : restores to battery when batteries have been installed
● Measurement data : saved until the last interval before an interruption
● Operation after interruption : recording restarts with preset settings if a power is interrupted during
recording. In this case, occurrence of interruption is recorded with time and date information. (STOP)
Restoration is also recorded as well. (START)
Instrument doesn’t power on again automatically when a power interruption occurs and restores other than
recording period.
Files in CF card or Internal memory may be destroyed if an AC power is interrupted while accessing to them.
Use of AC power supply and batteries at the same time is recommended if power interruptions are concerned.
