Page 6: Terminal Connections
Placement of Internal Adjusting Controls and Operation Keys “VPRVS” Series “VPRHS” Series 3. Terminal Connections Upper terminals Lower terminals For relay output (Types: 1S, 2S) Lower Upper terminals terminals For open-collector output (Types: 1SO, 2SO) Lower terminals Sensor connection A (+EXCITATION) Peak-holding terminal (activated when short-circuited together with the terminal No. - Page 7 Caution: The sensor power supply (EXCITATION) is the power supply for a sensor with VALCOM built-in amplifier. (If the power supply specification for the model (*2) specifies an AC power supply, the standard specification is 12 VDC, 25 mA.) (If the power supply specification for the model (*2) specifies a 24VDC power supply, the standard specification is 15 VDC, 40 mA.) .
- Page 8 * When you must perform calibration, follow the procedure described in "8. Maintenance, Inspection and Adjustment." (*While performing calibration, do not touch any control which does not need adjustment.) * When a measurable limit (FS.±approx. 2%) is exceeded, the display starts flashing. (The reading remains unchanged.) When zero-shifting has been performed, the zero-shifting amount is added to or subtracted from the original measurable limits.

Optional Peak-holding Function * Short-circuiting the terminal No. 10 (P) and the terminal No. 12 (COM.) activates the peak-holding function. * When the terminals are opened, the unit returns to normal measurement operation. ＊ P (Peak holding) Actual input Peak holding Reading Peak command...
- Page 10 Normally, this unit requires only zero adjustment for maintaining high accuracy. When this unit needs recalibration, send it to VALCOM or perform calibration by following the procedure below. 1) Prepare a calibrator with guaranteed accuracy. 2) If the input must correspond to the "0" indication, make sure that the indicated value is "0".
