A6 - LEAD BATTERY MAINTENANCE AND RECHARGE
• The analyzer has a + 12 V, 7 A built–in power supply with lead batteries.
• Low battery indications:
– + 1 beep: will appear 30 minutes before switch off.
– + 2 beeps: will appear 20 minutes before switch off
– + 3 beeps: will appear 5 minutes before switch off.
All the messages are repeated every 30 seconds and are accompanied by an audible tone, even if the volume is low.
Recharging procedure of the lead batteries provided with the analyzer:
a) Connect the adapter to the mains and insert the plug into the connector socket [27] (or in a vehicle using the optional
cigarette lighter adapter).
b) Turn off the DM14B/C and the BATTERY CHRG [15a] LED will light up (if the instrument is turned on, the batteries
will not recharge).
c) Keep the batteries under charge until the FULL BATTERY LED lights up [15b] together with the BATTERY CHRG
[15a] (batteries which are completely discharged require approximately 4 hours).
d) 50% of the charge can be achieved in about an hour.
Battery replacement procedure:
a) Open the upper cover of the instrument (not indispensable).
b) Unscrew the eight external screws in the back battery box.
c) Pull out the battery box, remove the two Faston clips, remove the four screws in the battery holder metal cage.
Replace the normal batteries with 12 V, 7 A Lead batteries, guaranteed for at least 200/500 loads.
NOTES:
• The "BATTERY CHRG" LED on the front of the DM14B/C lights up when the meter is recharging.
• The fully charged battery capacity is 4 hours at 25°C, and decreases considerably if the working temperature is higher
than 35°C or less than 10°C.
• The batteries do not recharge if the DM14B/C is on.
• Once the recharging procedure has been completed the BATTERY CHRG LED turns off and the FULL BATTERY
LED turns on.
• Once the battery is charged the battery charge automatically stabilizes and the meter can be connected to the mains for
as long as you like.
• As you know, lead batteries usually have overload problems. The batteries can be damaged indefinitely if they are left
discharged for more than 24 hours.
• In the DM-14 the battery discharge is controlled by a microprocessor, which turns off the instrument in order to
maintain the battery residual charge. This residual charge means that the batteries do not degrade without recharge for
a maximum of 3 months.
BATTERIES NOT UNDER GUARANTEE:
The batteries are a standard format: 12V 7 A Lead. They can be easily purchased from all distributors of electronic
components and electrical supplies, at a cost of approximately 5 Euros / $.
N.B. RO.VE.R. does not supply replacement batteries because the transport costs exceed the cost of the batteries.
