Tips regarding correct handling of batteries:
Do not leave used batteries in the instrument!
Remove batteries from the instrument if it is not used for a long period.
Risk to health and instrument failure can result from leaking batteries!
Therefore, only use leak-proof batteries.
Used batteries are hazardous waste and must be disposed in an
environmentally friendly way! Return them to the dealer or dispose of
them in a battery storage container.
Operation with rechargeable batteries:
Rechargeable batteries can be used instead of normal batteries. Due to their
smaller capacity of 110mAh they only reach an operating time of 16 hours. The
operating time will be shortened if sensors or modules are connected that
consume additional current. It is recommended to use the 9V rechargeable
battery with plug-integrated charger unit ZB 2000 LS, which is included in the
range of accessories.
Tips regarding correct handling of rechargeable batteries:
The rechargeable batteries supplied are not charged when delivered!
Therefore, they must at first be charged.
If NiCd cells are only partly discharged, the full capacity cannot be
reached by a normal recharging. Therefore, use the instrument until the
rechargeable battery is almost completely discharged and then
completely re-charge the battery again. As a result, the life of the
rechargeable batteries is significantly increased.
Completely recharged batteries will slowly discharge when they are not
being used and during storage. Therefore, they should be checked at
least once per month so they cannot suffer damage from deep
discharge.
3.2 External Voltage Supply
For an external voltage supply the connector socket (4) is located at the right
side of the device. The range of accessories includes the mains adapter ZB
2290-NA (12V/200mA). However, any other DC voltage source (7 to 13V) can
also be used. The connection is performed by a low-voltage connector (NES1
according to DIN 42323, centre pin to negative).
The electrically isolated supply cable ZB 2290-UK must be used if an electrical
isolation between power supply and transducers is required or if a larger input
voltage range is required. It allows to operate the measuring instrument with
12V or 24V mains supply.
If a battery is used in addition it will take over the power supply
if the voltage drops under 9V.
