6 PRE-OPERATIONAL CHECK

The CL526 portable calibrator is powered by four Ni-MH rechargeable batteries.

The external battery charger, supplied as standard, may be ordered for either 110/120 Vac or 220/240 Vac power source. To modify the charger’s power voltage follow the instructions in par. 8.2.

Before using the instrument carefully verify the nominal voltage value of the charger; in case of modification do not forget to correct the pertinent label.

The instrument should be used in environments where the temperature does not exceed the specified limits (from -5°C to +50°C) and where the relative humidity is lower than 95%.

Out 1248.3°C Tc

In case of “low” battery condition (voltage lower than 4.6 V) the display will show the appropriate symbol. An empty symbol means that the battery package has enough energy for about 30 minutes operation. A black symbol means that batteries charge is below the minimum acceptable level: operation of the instrument is no longer possible. In this condition the instrument batteries must be recharged.

WARNING

THE INSTRUMENT IS SUPPLIED WITH NI-MHRECHARGEABLE BATTERIES.

DO NOT USE NORMAL ALKALINE BATTERIES.

ALKALINE BATTERIES, WHEN CONNECTED TO A DC VOLTAGE SUPPLY UNDERTAKE AN OVERHEATING PROCESS WITH A RISK OF

EXPLOSION.
