Frequency: 10 Hz to 200 Hz; 0.2 Hz; ±(1.5 % + 2 digits); sine
When measuring voltages, the input resistance depends on the measuring range:
- Measuring range 1: 0 V - 25 V; Input resistance: 1.694 MΩ
- Measuring range 2: 25 V - 200 V; Input resistance: 1.05 MΩ
As soon as the total of all voltages exceeds 25 V, the measurement is switched over.
