| Analog monitor *1 | Outputs a voltage signal according to the current waveform or voltage waveform | ||||||
| I | Current waveform: Scale 50 mA/1 V | ||||||
| V | Voltage waveform: Scale 1 kV/1 V | ||||||
| Grounding mode (GND) | Can be switched between Low and Guard. | ||||||
| Low | GND is connected to the low terminal. Measures the current flowing across the low terminal and chassis (normal applications). | ||||||
| Guard *2 | GND is connected to Guard. Measures only the current flowing through the low terminal (cur-rent flowing through the chassis is not measured) (high sensitivity, high accuracy measure-ment applications). | ||||||
*1 Monitor signal output is isolated from the chassis (earth). If you connect an oscilloscope or an external device whose BNC shield is grounded, be sure to set the grounding mode (GND) to Guard. The value is not calibrated. *2 If there is a possibility that the EUT or tools and the like will be grounded or if you are uncertain, do not set GND to Guard. Doing so is extremely dangerous because the ammeter will be shorted and will not be able to measure current. For normal applications, set GND to Low.
