Yokogawa CA71 Handy CAL Calibrator

Fits field loop checks where you need a Yokogawa CA71 HANDY CAL to source and measure DCV/DCI/TC/resistance/frequency in one tool.

Key advantages

• Multifunction HANDY CAL — Portable multifunction HANDY CAL calibrator (CA71)
• Source + measure — DCV/DCI/resistance/TC/frequency/pulse source; simultaneous measure
• TC/RTD — TC K/E/J/T/N/L/U/R/S/B; RTD Pt100/JPt100 measure (CA71); built-in RJC
• Workflow — n/m divided output, auto-step, sweep, 50-set memory, RS-232
• Portable power — 4× AA alkaline or optional AC adapter; ~12–40 h depending on load; Approx. 190×120×55 mm; ~730 g including batteries

Typical applications

• Transmitter loop checks (4–20 mA source/sink) on the plant floor.
• Thermocouple simulation with built-in RJC.
• Resistance and frequency/pulse source tasks with auto-step/sweep.

Selection guide

• Source ranges — DCV DCV ranges 100 mV / 1 V / 10 V / 30 V; current 20 mA / 4–20 mA; 20 mA SINK from 5–28 V external
• TC types — TC K/E/J/T/N/L/U/R/S/B; RTD Pt100/JPt100 measure (CA71); built-in RJC
• Memory / interface — 50-set memory; RS-232.
• Power — 4× AA or optional AC adapter.

Common mistakes

• Assuming RTD source on every CA71 function — OEM lists Pt100/JPt100 measure on CA71; confirm source vs measure needs.
• Planning all-day mA sink without checking battery life vs load.
• Forgetting external 5–28 V for 20 mA SINK mode.
