INSTALLATION
The battery charger supplied is a ‘Smart’ charger.
!
WARNING: DO NOT use any other charger than that supplied
with this product.
The use of any charger other than that supplied for use will
invalidate the product warranty.
The smart charger goes through three charging stages:
• pre-charge
• fast-charge
• trickle
charge
If the battery has been damaged then the charger will not begin the fast-charge stage.
Please contact Michell Instruments’ service department for advice.
Once the charger has finished the fast-charge stage it can be safely disconnected.
Switch off the AC power supply, remove the charger unit and close the instrument’s
charge connector protection cover.
A complete charge cycle will take 2 to 4 hours for a fully discharged battery.
The table below shows the different charging stages and durations.
