(7) Next, calibrate the transfer output function. If the transfer output
function is not supported, skip to step (11). Press the
key. The dis-
play changes to [
] (20mA calibration display).
(8) Set the output to 20mA by the
or
keys while monitoring the
voltage on the digital multimeter. In the example on the left, the dis-
play indicates that the value two digits smaller than before calibra-
tion is “20mA”.
(9) Press 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 dis-
play indicates that the value two digits smaller than before calibra-
tion is “4mA”.
(11) Press the
key until the display changes to the data save display.
Press the
key. The No.2 display changes to [
], and two
seconds later the calibration data is saved to internal memory. If you
press the
key when the No.2 display reads [
], the calibration
data is invalidated.
(12) This completes calibration of the platinum resistance thermometer.
Press the
key to return the display to [
].
