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)
•
A voltmeter (YOKOGAWA 7561 or the equivalent)
•
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 (or those equivalent to 0, 6.25, 25, 56.25, and
100% of the input span if square root extraction is set) from
the voltage and current generator to the distributor.
3.
Then, check that the distributor’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.
