Temperature Scale
This instrument complies with ITS-90 and IPTS-68.
Connection Terminals
This instrument is equipped with the following two types of terminals.
TC-A (TC mini plug)
A thermocouple is connected to the instrument using a thermocouple mini plug set,
sold separately. Reference junction compensation using an external RJ sensor (sold
separately) is not possible.
TC-B (banana plug)
Reference junction compensation using the internal RJ sensor or an external RJ sensor is
possible.
Reference Junction Compensation
The instrument measures the temperature of the contact using an RJ sensor and generates a
voltage based on the temperature component. This instrument can perform reference junction
compensation using the internal RJ sensor or an external RJ sensor.
When an instrument with a built-in reference junction temperature compensation is to be
calibrated, the reference junction temperature of the device to be calibrated is measured using
an external RJ sensor.
