Calibrating the Instrument
Calibrating voltage measurement
• Use a generator that can output 7 V DC.
• For the connection between this instrument and the generator, refer to Figure illustrated below.
• You must not input the AC current of this instrument to the generator. This may cause a malfunction of the
generator.
• Use the generator with a low output impedance.
• Some of generators may not operate normally.

Calibrating temperature measurement
• Calibrate the standard resistor with Pt100 IEC Class A or equivalent.
• For the connection between this instrument and the generator, refer to Figure illustrated below.
• You must use the wiring resistance of both ways less than 10
Ω
.
• Use the connection terminals of
φ
3.5 four-terminal structure (For the four-pole signal cable, refer to Figure
illustrated below.)
