Electrical instrument workshop instrument section existing huasairui oxygen table 21 Taiwan (sets), each table consists of the high accuracy SR-2030 analysis shows that the instrument display. The operator can operate in the instrument panel, the analysis shows that the calibration instrument, the zero point range.

Instrument two classes of operators found in the calibration of 4# gas analysis instrument, instrument can process oxygen content of normal display, but press the function key can not enter the corresponding function menu, can not be zero calibration of transducer. The operator through the analysis of the instrument found key board cable part failure. The cable is too small can not be repaired, and a plurality of the sample tables appear similar problem, so they use the old table components modified cable keypad detachable, need calibration as long as the cable that after the transformation of key board is inserted into the instrument can carry out the operation, solve the calibration problems because the cable fault can not, to ensure the stable operation of metering equipment.
