6 Recharging CalMaster2
CalMaster 2 incorporates an intelligent charger that features fast, high and low current charge
modes. The unit switches automatically from high current to low current charge mode when the
required battery voltage is reached.
CalMaster2 must be recharged after use for at least four hours. With a full charge, CalMaster2 can
verify a minimum of six flow meters before needing to be recharged.
To recharge CalMaster2:
1.
Plug in the universal mains adaptor
A
– see Fig. 6.1.
2.
Press the 'On' button
B
. Failure to do this results in slow and partial charging of the
battery.
3.
Correct connection is confirmed by the mains icon in the top right corner of the display
C
.
4.
The display shows the normal start-up screen (
). After a short time period with no
activity, this screen times out. If at this stage the CalMaster 2 determines that a fast-charge
is necessary, the display shows the text 'Fast Charging x.xV', otherwise, the display
switches off (enters sleep mode) immediately.
5.
If fast-charging mode was engaged, once the required battery voltage is reached the unit
switches fast-charge off automatically and the display switches off. Pressing the 'On' button
B
starts the CalMaster 2.
6.
Typical charge periods are about 4 hours.
7.
CalMaster 2 can be used during charging by pressing the button labelled 'Stop' on the
display, followed by the 'On' button
B
. Leave the charger connected. In this mode, charge
times are extended.
