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 frequency is not within 40 ~ 70Hz, all
the parameters (except for voltage and current ) cannot be computed and thus displayed. In such a case,
the numerical digits will be replaced by a bar indication (“- - - -”) as shown:
Zero Indication
Zero “0” is displayed when measured items exceeds following conditions.
Voltage : Voltage Range x VT ratio x 5% e.g. Voltage Range : 300V, VT ratio : 1 => 15V
Current : Current Range x CT ratio x 1% e.g. Current Range : 200A, CT ratio : 2 => 4A
“-------“ is displayed.
0 is displayed.
