9. 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.
9.1 Calibration Apparatus
• A calibrator (YOKOGAWA CA150 or equivalent)
•
A precision resistor of 250 Ω ±0.01%, 1W
• Setting tool for adjustment (Refer to
9.2 Calibration Procedure
1. Connect the instruments as shown below. First adjust the
output-1 signal and then the output-2 signal.

2. Use the calibrator and apply input signals equivalent to 0, 25,
50, 75, and 100% of the input span to the product.
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 “8. LIST OF PARAMETERS” in this manual.
