The Model HCVC is a portable calibrator designed to meet the requirements of field-calibration, testing, and troubleshooting of transducers, transmitters, actuators, and other process and control devices.
The Model HCVC features a large, 0.59” (15 mm), LCD numerical display, with blue backlighting for use in dimly lit areas. Powered by a readily available standard 9V battery, it also comes with a 120 V AC plug-in power supply for bench-top use.
0.0 to 20.0 mA DC output in 1.0 mA steps.
0.0 to 10.0 V DC output in 1.0 V steps.
Three output modes automatically selected by plug location.
Simulate using external loop supply (30 V DC Maximum).
Source using internal 9V battery.
Voltage-output.
Auto-ramping with user-adjustable minimum & maximum output values.
User-adjustable ramp step time, 1 to 20 seconds, in 1 second increments.
User-adjustable auto-power-off time from 1 to 20 minutes in 1 minute increments.
3-Position bail for pocket, hanging, or bench-top use.
Complete with:
- 9V battery.
- 120 VAC plug-in power supply.
