8. MAINTENANCE
The product starts running immediately when the power is turned
on; however, it needs 10 to 15 minutes of warm-up before it
meets the specified performance.
For cleaning the instrument, use a soft and dry cloth.
8.1 Calibration Apparatus
• A voltage and current generator (YOKOGAWA GS200 or the
equivalent)
• Digital Multimeter (YOKOGAWA 7561 or equivalent): 1
• A precision resistor of 250 Ω ± 0.01%, 1 W (for current output)
• Setting tool for adjustment (Refer to "4.2 Connector for
Communication" in this manual.)
8.2 Calibration Procedure
1. Connect the instruments as shown in figure below. First adjust
the output-1 signal and then the output-2 signal.

2. Produce input signals equivalent to 0, 25, 50, 75, and 100%
of the input span from the voltage and current generator to the
isolator.
3. Then, check that the isolator’s output signal shows voltages
corresponding to 0, 25, 50, 75, and 100% of the input span
within the rated accuracy range.
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.
