  • Page 172 12.TROUBLE SHOOTING (Calibration error) Zero Calibration must be entered again. Zero Calibration should always be done before Span Caibration. If “ ” appears after Calibration, Zero Calibration must be entered again. After Zero Calibration “ ” will disappear. (Calibration error) Initial dead load is above zero adjustment range.
  • Page 173 The set Balance Weight Value is “00000”. Set adequate value to Balance Weight Value. (Calibration error) he load cell output dose not reach the span adjustment range of the F701-C. Check how load is applied to load cell; check load cell has sufficient outpul (mV/V) to reach span range.
  • Page 174 STAB Calibration. Do Calibration again. The span adjustable range of the F701-C is 0.3 ~ 3.2 (mV/V). Since display to the Capacity is guaranteed in Span Calibration, calibration cannot be performed if the load cell output is under 0.3 (mV/V) ( ) or exceeds 3.2 (mV/V) (...
  • Page 175 The setting values stored in the SRAM (refer to "18.THE LIST OF INITIAL SETTING VALUE" on P.176) are backed up by the lithium battery. If the power of the F701-C is turned off with the voltage of the lithium battery having dropped, the setting values are lost.
  • Page 176 It is displayed if a checksum error occurs in self-checking or at power-on. (NOV RAM check error) It is displayed if a NOV RAM check error occurs in self-checking. * In the case of self-check error display, the F701-C is faulty. Request repair from your distributor or us.

  • Page 177: 13．Replacement Of The Backup Battery

    The life of the lithium battery for memory backup is approx. 7 years. For replacement of the battery, send the F701-C to us in a manner similar to repair. Since the setting values in the “SRAM” (refer to "18.THE LIST OF INITIAL SETTING VALUE" on P.176) are lost when the battery is removed, record the setting values beforehand.
