4.Calibration procedures

Warning ● Before using the new instrument or after exchanging the strain gage appliedtransducer with a new one, be sure to make calibration.If calibration is not made, correct measured results may not be obtained, or it maycause malfunction to the instrument and it may damage the peripheral equipment.Moreover, even if calibration has made, there may occur the similar case as abovewhen the result is not correct. So make precise calibration again.

● The calibration for the instrument and “Display value at the time of minimum analogoutput”(F−21) and “Display value at the time of maximum analog output” (F−22) arenot interlocked. In due course, make check on the setting for F−21 and F−22 securely.If neglected, correct outputs may not be obtained, or it may cause malfunction to theinstrument and it may damage the peripheral equipment.

4−1. Preparations

According to the Chapter 3. Connecting method, connect the instrument and the signal wires input

the voltage properly, then supply the power.

4−2. Calibration procedures

The display calibration procedures against the voltage input for this instrument are as follows：

1 Calibration method to register the input voltage value at the time of full scale display after

setting the input voltage to 0 V.

2 Calibration procedure to register by the reading the input voltage value in the condition of 0 V

and in the condition of inputting the voltage equivalent to the value at the full scale

individually.

3 Fine adjustment on Zero

4 Fine adjustment on Span

5 Calibration procedures to apply registration again for zero point only.

6 Compensation of symmetric property(Fine adjustment of minus side span)

● The accuracy of calibration obtained from① is 1/1 000 or so. If the accuracy morethan 1/1 000 is required, make calibration of② type.

In the following paragraphs, we will describe each calibration procedure by showing theexamples with load cell applied.

4−2−1. Calibration method to register the input voltage value at the time of full scale display after

setting the input voltage to 0 V.

Warning ● Before using a new instrument, or when the input voltage specifications is changed, orexchange the pressure transmitter for a new one, be sure to make the calibration. Ifcalibration shall not be made, correct measured results may not be obtained nor itmay cause malfunction in the instrument and there may exist damage to theperipheral equipment.Besides, even though the calibration has been made, there may occur the similar casewhen the result is not correct, so make calibration again.

● During the calibration is executing, be sure to make cancellation (Execution of F−98)for compensated data on zero set

● When the changeover target of the calibration data is set to the changeover byexternal control input(Setting of F−80： “00001” or “00011”), execute the calibrationafter the changeover of the calibration data changed by the external controloutput(SEL.1 and SEL.2).

● During calibration procedures, press the key in case of interrupting thecalibration is required. The calibration data will be kept as they are before enteringthe calibration and then returns to the Measurement mode.

● Every time the key is pressed with the setting display section of “FUNC”, the

display will change as the following arrow marks. However, every time the key ispressed, the display will change as the reverse direction of the following arrow marks.“FUNC”→“CCAL”→“LCAL”→“ZERO”→“SPAN”→“TARE”→“CHEK”→“MONT”→“VCAL”→“VADJ”→“SYMM”→“FUNC”→“CCAL”→･････(Hereinafter, it will repeat.)
