Measuring currents and voltages
Measuring currents and voltages used
The following measuring currents and voltages are used, depending on the measuring range.
Measuring range | Typical measuring voltage (max.) | Typical measuring current. |
|---|---|---|
-1 (0 -100 mΩ) | ~ 4.5 mV (3.0 V) | ~ 45 mA |
0 (100 mΩ -1 Ω) | ~ 45 mV (3.0 V) | ~ 45 mA |
1 (1 Ω-10 Ω) | ~ 450 mV (3.0 V) | ~ 45 mA |
2 (10 Ω-100 Ω) | ~ 16 mV (3.0 V) | ~ 0.16 mA |
3 (100 Ω -1 kΩ) | ~ 160 mV (3.0 V) | ~ 0.16 mA |
4 (1 kΩ -10 kΩ) | ~ 1.6 V (3.0 V) | ~ 0.16 mA |
5 (10 kΩ -100 kΩ) | ~ 16 mV (3.0 V) | << 16 µA |
6 (100 kΩ -1 MΩ) | ~ 160 mV (3.0 V) | << 16 µA |
7 (1 MΩ -10 MΩ) | ~ 1.6 V (3.0 V) | << 16 µA |
