Measuring frequency: 77.5Hz; Test current: 12mA; Open loop voltage: < 25Vrms
Disturbance voltage on ampere and volt circuits: the measurement is taken with the stated accuracy if the interfering
voltage is 3V, while for interfering voltages ranging from > 3V and 9V, the accuracy decreases progressively;
with an interfering voltage equal to 9V the instrument does not perform the test
