4.5 Calibration
E5CK
4--19
This example describes how to calibrate voltage input when the transfer
output function is supported. If the transfer output function is not sup-
ported, skips steps (4) to (7).
(1) When [
] is displayed, the 30-minute timer is displayed on the
No.2 display and counts down. This timer serves as a guide for the
aging time when aging is required.
(2) Press the
key. The display changes to [
] (10V calibration
display). Set the STV output to 10V. When the value on the No.2 dis-
play has stabilized (changes of several digits max.), press the
key
to temporarily store the calibration data.
(3) Press the
key. The display changes to [
] (0V calibration dis-
play). Set the STV output to 0V. When the value on the No.2 display
has stabilized (changes of several digits max.), press the
key to
temporarily store the calibration data.
(4) Next, calibrate the transfer output function. If the transfer output
function is not supported, skip to step (8). Press the
key. The dis-
play changes to [
] (20mA calibration display).
(5) 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”.
(6) Press the
key. The display changes to [
] (4mA calibration
display).
(7) 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”.
(8) 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.
(9) This completes calibration of voltage input (0 to 10V). Press the
key to return the display to [
].
