8. MAINTENANCE
The product enters the operable status as soon as the power is
turned on, but requires 10 to 15 minutes of warm-up to meet the
performance requirements.
8.1 Calibration Apparatus
• A voltage and current generator (YOKOGAWA GS200 or the
equivalent): 1
• 6-dial decade resistance box (YOKOGAWA 279301 or
equivalent): 1
• Digital Multimeter (YOKOGAWA 7561 or equivalent): 1
• Precision resistor of 250 Ω ±0.01%, 1 W: 1
• Setting tool for adjustment (Refer to "4.2 Connector for
Communication" in this manual.)

2. For TC input
• Turn off the RJC through the setting tool.
• Use the DC voltage/current standard and apply input
signals (electromotive force) equivalent to 0, 25, 50, 75,
and 100% of the input to the converter.
For RTD input
• Use 6-dial decade resistance box and apply input signals
(resistance value) equivalent to 0, 25, 50, 75, and 100% of
the input to the converter.
For mV input
Use the DC voltage/current standard and apply input
signals equivalent to 0, 25, 50, 75, and 100% of the input
span to the converter.
3. Check to see the corresponding output voltages are 0, 25, 50,
75, and 100% respectively and within the specified accuracy
rating. (“R” is used for current output.)
For alarm output, check the relay action by the alarm indicator
lamp or resistance of output terminals.
• When adjusting the output signal, use the VJ77 parameter
setting tool.
For adjustment using a setting tool, refer to the User’s Manual for
setting tool and “7. LIST OF PARAMETERS” in this manual.
