| Safety: |
Conforms to EN 61010-1, Main instrument Class 111 (SELV), Battery pack Class 111 (SELV), external mains charger Class 111 |
| Dimensions: |
390mm x 160mm x 270mm (W H D) approx |
| Mass: |
4kg approx |
| Protection: |
415 Vrms maximum at input terminals |
| Battery: |
The DO7010 is supplied with battery fitted. The batteries are NiMh and the charger is external. The battery pack may be removed from the front panel when discharged and a replacement charged pack inserted. This ensures minimum down-time when making measurements |
| Remote Terminal: |
The remote terminal emulates the DO7010 front panel and all functions and readings are fully controllable up to 15 metres from the ohmmeter. Connection is made through the RS232 terminal |
| Lead Sets: |
We offer a wide variety of lead sets with 3 sizes of Kelvin clip or handspikes. Lead lengths may be up to 100 meters total loop |
| Data Logging: |
The DO7010 has data logging modes. The first will store each reading with record number date and time. The second is a sequence mode which will store values with operator ID, serial number etc |
