KEW6310 6.22
Bar Indication
The calculations and measurements performed by this instrument are based on the voltage and frequency
of V1. If the value of V1 is less than 5% of the chosen range or if the fre quen cy is not w ithin 40 ~ 70Hz, al l
the parameters (except for voltage and current ) cannot be computed and thus displayed. In such a case,
the numeric al digits will be replaced by a bar indication (“- - - -”) as shown:
Zero Indication
Zero “0” is display ed w hen me asured i tems e xcee ds fo llow ing condi tions.
Volt age : V ol t age Range x VT ra tio x 5% e.g. Voltage R ange : 300V, VT ratio : 1 => 15V
Current : Current Range x CT ratio x 1% e.g. Current Range : 200A, CT ratio : 2 => 4A
