Industrial Instrument Process Loop Calibrator Signal Source 7221

• Compact handheld structure (190 mm L × 89 mm W × 42 mm H)
• Solid anti impact body (drop tested in one meter height)
• Multifunctional: 2 in 1 calibrator combine with signal simulator and receiver
• High accurate input/output: mV, mA, V DC calibration signal (0.015 ~ 0.02%)
• Easy to carry and use: a handhold loop power supply source (24 V DC+/-10%) and signal source (4 ~ 20 mADC @ 0.015% + accuracy, 1 ~ 5 VDC @ 0.02% accuracy)
• Easy for checking linear, hysteresis and dynamic response
• Strong and solid body structure: One meter drop tested
• A must-have professional tool: Idea for calibration of primary, secondary instruments, and loops
• Output high accurate calibration signals (1 ~ 5 V DC, 4 ~ 20 mA DC), and no need of external high accurate 250 ohm resistor
• Output any scale ratio points between 0 ~ 100 % for linear span check correspond to 4 ~ 20 mA DC
• Measuring (input) mA, V DC signal of instrument, and loop
• Field transmitter simulation output
• Larger LCD display window
• 1,000 ohm drive capability @ mA application
• External easy battery change
• Over current fuse protection
• Professional technical support with more than 20 years in industrial process control
