To Ensure Safe Usage
The bridge check function shows the error information - that indicates the wire-breaking location - on the monitor.
Note that if 2 or more wires are broken, the bridge check function shows the error information of only one wire.
- DPM-911B Frequency Response: DC to 2.5 kHz
- DPM-912B Frequency Response: DC to 5 kHz
- DPM-913C Frequency Response: DC to 10 kHz
