Remarks

For bi-directional deflection meters, please choose a specification according to the following.
For direct rating, manufacturing is possible if the larger of the left and right scales is 30 A or less.
For combined use with a shunt, please choose a scale so that the sum of the absolute values of the meter ratings is 60 mV or more.
Example: For a shunt rated 100 A, 60 mV
Ammeter scale -50 to 0 to +100 A
Ammeter rating -30 to 0 to +60 mV
(sum of absolute values = 90 mV ≧ 60 mV)
