Measurement Of Ac, Ac+Dc Voltage With Low Impedance (Loz); Measurement Of Voltage Or Current On Vfd Devices - HT ECLIPSE HT9025 User Manual

4.3.8. Measurement of AC, AC+DC Voltage with low impedance (LoZ)

This mode permits to perform the AC/DC voltage measurement with a low input
impedance in way to avoid the wrong readings due to stray voltage in capacitive coupled.
1. Select the position LoZAC+DC
2. Press key MODE/VFD by selecting modes "V
3. Press the MODE/VFD key and select the models
4. Follow the operating instructions shown in § 5.1

4.3.9. Measurement of Voltage or Current on VFD devices

This mode permits to perform AC voltage or current evaluation downstream to VFD =
Variable Frequency Drivers devices.
1. Select the position VAC+DC
2. Press key MODE/VFD by selecting modes "V
3. Long press key MODE/VFD selecting "VFD" mode (see Fig. 11)
4. Follow the operating instructions shown in § or § 5.9
5. Long press key MODE/VFD again or turn the selector switch to quit the function
