In the above figure, STV refers to a standard DC current/voltage source,
and DMM refers to a precision digital multimeter. However, note that
the DMM is required only when the transfer output function is sup-
ported.
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 [
play). Set the STV output to 5V . When the value on the No.2 display
has stabilized (changes of several digits max.), press the
temporarily store the calibration data.
(3) Press the key. The display changes to [
play). Set the STV output to 0V . When the value on the No.2 display
has stabilized (changes of several digits max.), press the
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
play changes to [
(5) Set the output to 20mA by 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 [
display).
(7) Set the output to 4mA by 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 [
seconds later the calibration data is saved to internal memory. If you
press the key when the No.2 display reads [
data is invalidated.
(9) This completes calibration of voltage input (0 to 5V , 1 to 5V). Press the
key to return the display to [
