Use leads of the same thickness when connecting to the platinum resis-
tance thermometer.
In the above figure, 6-dial refers to a precision resistance box, and DMM
stands for a digital multimeter. However, note that the DMM is required
only when the transfer output function is supported.
Connect (short) the leads from terminal Nos. 6 and 7.
This example describes how to calibrate a platinum resistance thermome-
ter when the transfer output function is supported. If the transfer output
function is not supported, skips steps (7) to (10).
(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) First, calibrate the main input. Press the
(300 calibration display). Set the 6-dial to 300 . When the value on
the No.2 display has stabilized (changes of several digits max.), press
the key to temporarily store the calibration data.
(3) Press the key to switch [
terminal No.6 to 8. When the value on the No.2 display has stabilized
(changes of several digits max.), press the
store the calibration data.
(4) Next, calibrate the B-B' input. Change the wiring as follows.

Make the connection across terminals 6 and 7 and the 6-dial as short
as possible. Short terminals 6 and 8.
(5) Press the key to display [
6-dial to 10 .. When the value on the No.2 display has stabilized
(changes of several digits max.), press the
store the calibration data.
(6) Press the key to display [
6-dial to 10 .. When the value on the No.2 display has stabilized
(changes of several digits max.), press the
store the calibration data.
