Remark 1. Scale intervals for the movable iron core-type meters are non-uniform, and scale lines near the 0 point of the scale are omitted.
Remark 2. Scale lines and number positions may differ slightly between individual meters, even with the same scale specifications.

Expanded Scale Meters

Use in locations where overcurrents flow temporarily, such as motor circuits.
The effective measurement range covers up to the meter rating value (1x value.) The expanded scale portion is displayed to provide reference values.
Ensure that during application of a current exceeding the rating (applied current [A] / rated current [A])2 × the application time (s) does not exceed 500.
