|
Power Supply
|
Time Electronics power unit type PU2 which is housed in the rear of the 1024. The PU2 will power the 1024 direct from the mains or an internal rechargeable battery. The battery is automatically charged when mains power is connected. Access to the power supply is from the back of instrument.
|
| Battery Level Indicator |
A front panel display provides a continuous indication of the battery state. |
