Current & Voltage Calibrators/Meters
Precision “source” for calibrating process devices
And measuring DC process signals from 0 to 24mA and 0 to 20V
Features:
• Upgraded models now feature super large
LCD display and touch keypad
• LCD displays readings in mA or as a % of the
0 to 24mA range or as mV in voltage ranges
• Five stored calibration values for fast calibrations
• 412355A Current + Voltage Calibrator provides
adjustable 0 to 24mA and 0 to 20V calibration source
• 412300A Current Calibrator provides 0 to 24mA output
displayed as mA or % and provides 24VDC power to
measure a two-wire current loop
• Complete with 9V battery, calibration cable with
spade lug terminals, carrying case, and
100V-240V AC Universal Adaptor (50/60Hz)
Applications:
• Setup and calibration of process devices such as
transducers, indicators, recorders and controllers
• Troubleshooting and Field service
• Product design
