The CL526 portable calibrator is powered by four
The
Cyclic operation is understood as a method of operation by which the battery is continually charged and discharged. Note that a battery, at its lower limit of discharge, risks a non uniform cell polarization: this condition makes it difficult to recharge with the charger supplied.
Avoid leaving the instrument, with batteries totally or partially discharged, for a long time without recharging.
To charge the batteries use only the original supplied charging module. The module incorporates protection and current limiting devices not normally found in other commercial chargers.
•When the CL526 is connected to the battery charger module, by pressing keys <SHIFT> + <BATTERY> the following indication will be displayed:
Battery: Line Op
If a numeric value appears, it indicates that the charger is probably faulty.
Replace the battery charger module; if the indication persists, contact OMEGA

8.3How to maximize the battery life
Disconnect the ac mains supply when the battery is charged. Use the battery until it is completely discharged. Leaving the ac mains supply plugged in will decrease the life of the battery.
Keeping the battery terminal clean will help maximize the operating time. Periodically wipe the positive and negative terminals with a dry cloth.
Removing and replacing the batteries will ensure electrical contact. This should be done when using a battery that has not been used for a long time.
Note that the operating time decreases at low temperatures.
