4. 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.
4.1 Calibration Apparatus
• A DC voltage/current standard (YOKOGAWA GS200 or the
equivalent)
•
A digital multimater (YOKOGAWA DM7561 or the equivalent)
•
A precision resistor of 250 Ω ± 0.01%, 1 W
4.2 Calibration Procedure
1.
Connect the instruments as shown below. First check the
channel 1 signal and then the channel 2 signal.

2. Use the DC voltage/current standard 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.
