6. INSPECTION AND CHECK PROCEDURES
Measurement
(1) Turn on the printer.
(2) Use the voltage generator to successively input the reference voltage signals for each range to the 0°C
reference temperature device (zero control) according to the table below, then check that the printed
level of measurement is within the rating.
Temperature ranges:
Standard 1 : When measurement is continued right after setup
-
200°C to 0°C: ± (0.5% of rdg + 1.5°C)
0°C to 400°C: ± (0.2% of rdg + 1.5°C)
Standard 2 : When measurement is continued under different conditions than setup (main unit, mea-
surement site, insertion slot)
-
200°C to 0°C: ± (0.5% of rdg + 2.0°C)
0°C to 400°C: ± (0.2% of rdg + 2.0°C)

6.2.5 Signal-to-Noise Ratio
Preparation
Prepare the short terminals shown below for shorting the + and
-
terminals for each channel of the target amp,
then short those terminals.
Fig. 6-2-8
NOTE
If there are not enough short terminals to short each channel separately, set the RANGE setting for each
of that amp’s channels to Off.
