Using an external power supply
More demanding applications, such as an extended base-station operation,
may require more power than can be provided with the either of the
SCINTREX supplied battery packs. In this case you have two options:
1. AC-power
If a source of AC-power is available, the instrument can be run while the
charger is connected to it. You will also be charging the standard
internal battery, if it is installed, at the same time.
Note: Please be aware of possible magnetic noise from generators, and
ensure that all cabling and sensors are as far away as possible from
the generator as possible.
2. 12-volt battery (car or marine)
A 12-volt car battery may be more appropriate for other applications.
The special External Power Cable (SCINTREX P/N 788 029) should be
used for this purpose.
1. The standard internal battery may be left in place.
2. Plug in the end of the cable with the single plug into the Charger
Connector at the right-rear side of the ENVI-MAG console. (See item
6 in Figure A-9 on page A3-2.)
3. Connect the end with the clips to the battery terminals. The red
cable-clip goes to the positive battery terminal. The black cable-clip
goes to the negative battery terminal.
Caution: The correct polarity must be used for the instrument to
operate properly.
