| Output Connections |
The output is via low thermal emf terminals (0.2μV/°C). A mains earth terminal is provided for screening purposes. Output polarity can be selected by a switch on the front panel. |
| Power Supply |
The 1017 can be powered continuously from a 230V 50/60 Hz (110V to order) mains supply, or from the internal rechargeable NiCad battery pack. |
| Battery Level Indicator |
A front panel display provides a continuous indication of the battery state. |
