RS232 interface cable.

3.1.4 Power supply

3.1.4.1 Batteries and storage batteries

Both models, MiniTest 7400 FH and MiniTest 7200 FH, are powered by a set of four alkaline-

manganese cells, 1.5V, AA LR6 size (Batteries included in the standard supply schedule.).

As an alternative, both models may be operated on rechargeable NiMH (type AA-HR6) storage

batteries or via a power supply unit (available as an option). Please use only products as

recommended by ElektroPhysik (See section 14.3, Accessories).

If you wish to use the storage batteries, they must be recharge using the external charger unit

(available as an option). Please also refer to section 13.1 “Care and maintenance” for more details.

Note:

•

Remove batteries or storage batteries from the instrument if you are not going to use it for a

longer period of time.

•

The battery symbol on display indicates the battery state.

•

For field use, replacement batteries should be made available.

•

Erratic readings due to low battery voltage do not occur because the gauge switches off or

does not switch on if the battery is too low.
