In the above figure, STV refers to a standard DC current/voltage source.
(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 [
display). Set the STV output to 5VDC. When the value on the No.2 dis
play has stabilized (changes of several digits max.), press the
to 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) 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.
(5) This completes calibration of voltage input (0 to 5VDC, 1 to 5VDC).
Press the key to return the display to [
