Note: Accuracy specifications are valid above 100 counts. For current and power measurements,
specifications apply from 2% to 100% of measurement range. Current and Power range and accuracy
specifications are times three for MX45-1, MX60, MX90 and MX135 or MX30-3Pi / MX45-3Pi in single-
phase mode.
Note: Power factor accuracy applies for PF > 0.5 and VA > 50 % of max.
