2.5 Connecting the Power Supply
Operating power is provided by an internal battery that can be charged from the utility supply using
the supplied external charger. When you first receive the unit you must put the battery on charge for
a minimum of 6.5hrs before use. A fully charged battery will power the instrument for up to 20hrs
depending on the output utilisation and backlight usage.
2.5.1 Charging the battery
1. Connect the external battery charger to the charger socket at the bottom of the instrument then
switch on the utility supply.
2. When switched on, the instrument indicates charging with an animated battery symbol to the
left of the date.
3. Leave the instrument on charge for at least 6.5 hours before using it for the first time.
2.5.2 Optimising battery life
The backlight can be configured in the Setup Instrument menu (see page 18) to be either
permanently OFF, timed to switch off after 5-120s of keypad inactivity, or permanently ON. If the
backlight is active continuously it will reduce the available battery operating time to 8 hrs. Similarly, if
the 4-20mA output is used constantly at 20mA, the battery life would reduce by 50%. It is therefore
beneficial to turn off the backlight and 4-20mA output facilities when they are not required.
When the instrument is operating in the Flow Reading mode the percentage battery charge level is
displayed symbolically on the LCD screen. A warning message is triggered if the charge falls to
approximately 30%, at which point there is up to four hours of battery operation remaining,
depending on usage. The battery can be charged both while the instrument is in use or when
switched off. The instrument’s internal data is stored in non
-volatile memory and will not be lost
even if the battery discharges completely.
THE BATTERY IS NOT A USER-CHANGEABLE ITEM. THE INSTRUMENT MUST BE
RETURNED TO YOUR DISTRIBUTOR IF THE BATTERY NEEDS REPLACING.
ONLY USE THE SUPPLIED CHARGER, OR SPECIAL ADAPTOR LEAD. FAILURE TO
COMPLY WITH THIS WILL INVALIDATE YOUR WARRANTY.
