11.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.
11.1 Calibration Apparatus
● A voltage and current generator (Yokogawa 7651 or the
equivalent)
● A voltmeter (Yokogawa 7562 or the equivalent)
● A precision resistor of 250 ⍀ ± 0.01%, 1 W (for current output)
11.2 Calibration Procedure
Connect the instruments as shown in Fig. 10.1. First adjust the out-
put-1 signal and then the output-2 signal.
Produce input signals equivalent to 0, 25, 50, 75, and 100% of the
input span from the voltage and current generator to the isolator.
Then, check that the isolator’s output signal shows voltages corre-
sponding to 0, 25, 50, 75, and 100% of the input span within the
rated accuracy range.
If the output signal is out of the rated accuracy range, adjust the
output signal level using the Handy Terminal (JHT200).
