6-2-2. Output Adjustment
① Default analog output value is 4mA(weight zero) , 20mA(Full using capa).
② The analogue output value is adjusted with DIGITAL MULTI-METER.
③ How to adjust analog output value.
Step1) Connect Digital multi meter to the Indicator (A out terminal).
Step2) Enter “F-function HF14 Minimum Analog Output Setting” mode.
Step3) Adjust the displaying value of indicator with keys(by 9,999) to make Digital multi meter’s
value as minimum(ex:4mA) and save.(When the SI 460C indicate about 5,200 , the Digital
multi meter indicates about 4mA)
Step4) Enter “F-function HF15 Maximum Analog Output Setting” mode
Step5) after connect digital multi meter to the indicator, then adjust the displaying value of
indicator with keys (by 32,768) to make Digital multi meter’s value as maximum (ex:20mA).
※ This D/A Converter has Max 1/5,000 accuracy, so this output is not suitable for high
accuracy application, more than 1/5,000.
Check the setting to use the analog
output switch in the upper main
boad.
(Default : 4~20mA)

Select Switch
Under Calibration mode or “CELL-ERR” condition, Analogue output will not activated.
If the output is deactivated, the last output signal value will be hold until next activation.
