i. Ensure that the battery is fully charged. In this way it will not degrade for periods of
non-use up to 1 year.
ii. Open the instrument case by removing the two retaining screws located at the edges
of the instrument base. Remove the cover of the instrument, leaving the front and
rear panels located in the base. The battery will be seen supported on the rear panel
of the instrument. (See Figure 6.)
iii. Remove one of the push-on battery connectors and tape it to the side of the battery.
WARNING:
The battery can deliver a current of several tens of amperes. Do not, under any
circumstances, allow any conductive material to form an electrical pathway between the
positive and negative terminals of the battery.
iv. Replace the instrument top cover.
Note:
To maintain the life span of the internal rechargeable battery it should be recharged
at least once a year.
4.4. The Autoranging Display
The front panel LCD reads directly in
m
T when the instrument is used with the low field (0.2mT)
Mag probes type B, C and F. Display values should be multiplied by 10 to obtain true readings
when using the high field Mag probes (2.0mT) type D, E and G.
The display is autoranging. It provides three places of decimal resolution at low values (<10.000)
and two places of decimal resolution if values exceed 20.000.
Built-in hysteresis prevents undesirable range hopping.
Should the full-scale range of
±
199.99 be exceeded, the LCD will over-range and the display will
show
±
1______.
