*1 Instantaneous frequency is displayed even if conversion 

mode is pulse integration.

*2 The Status is displayed for service personnel to see 

history records.

*3 There are items not displayed depending on what output-2 

is specified.

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 

"4.2 Connector for 

Communication"

 in this manual.)

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.
