ERROR

6

When in mV or Tc “OUT” function the current flow must not

exceed 0.5 mA.

ERROR

7

Indicates a possible error during scale factor computation.

 

The above indicated faulty conditions can be announced both during the autodiagnostic routine or in measure or simulation modes.

If the faulty condition is critical for the type of application, it is recommended to re-run the pertinent set up procedure.

11.3Protection fuses

The CL526 unit, is protected against overvoltage and overcurrent inputs, by thermal fuses. When they activate, you should disconnect the electrical connections from the unit and switch the instrument off for about 2 minutes. The thermal fuses will be automatically restored and you can resume your work.

11.4Storage

If the instrument is left unused for a long time, it is recommended to remove the batteries.

Store the instrument in the original package, at a temperature from -30°C to +60°C, with R.H. less than 90%.

If the instrument has been unused for a month check the battery voltage, and charge the Ni-MH batteries for at least 12 hours.
