(6) Pr ess the

key to display [ ](0Ω calibration display, Short

terminal Nos. 11 to 13. When the value on the No.2 display has sta-

key to tempo-

rarily store the calibration data.

(7) Next, calibrate the transfer output function. If the transfer output

function is not supported, skip to step (11). Press the

key. The

display changes to [

] (20mA calibration display).

(8) Set the o utput to 20mA by the

or keys while monitoring

the voltage on the digital multimeter. In the example on the left,

the display indicates that the value two digits smaller than before

calibration is “20mA”.

(9) Pr ess the

key. The display changes to [ ] (4mA calibration

display).

(10) Set the output to 4mA by the

or keys while monitoring the

voltage on the digital multimeter. In the example on the left, the

display indicates that the value two digits smaller than before cal-

ibration is “4mA”.

(11) Press the

key until the display changes to the data save dis-

play. Press the

key. The No.2 display changes to [ ], an d

two seconds later the calibration data is saved to internal memory.
