Specifications - Model CA11E-1

Features Source and Measuring of Voltage and Current: Generates and measures voltages up to 30 V DC and currents up to 24 mA DC.
Improved display resolution for current: The generation/measurement resolution has improved to 0.001 mA.
24 V (20 mA)/Loop check function: Enables measurement of generated current signals while supplying loop power to two-wire transmitter. Load current: Max. DC22 A
20 mA SINK Function: Absorbs the voltage supplied from an external power supply to its H terminal and simulates a two-wire transmitter making it ideal for loop checks.
4-20 mA and 1-5 V DC Step-up/down Function: The output level can be changed between 4-8-12-16-20 mA signals by one touch for the 4-20 mA DC output, and between 1-2-3-4-5V signals for the 1-5 V DC output, for efficient calibration work.
Sweep Function: Increases and decreases the output level to the preset level at a constant rate for the selected sweep time (16 or 32 seconds). The sweep function and sweep time are set by the internal dip switches.

Additional Features

  • Automatic Power-off
    Power is turned off automatically if the calibrator is not touched for 10 minutes, prolonging battery life.
  • Runs on 1.5 V AA-size Batteries or AC Adapter
    The handy calibrators can run on the built-in 1.5-V ANSI batteries or an AC power supply using the AC adapter (sold separately).
  • Longer Lead Cables
    The slightly longer than usual lead cables of 1.7 m (approximately 0.1 Ω for both cables) allow easy cable connection even if the handy calibrator is put on the floor.
  • Compact and Lightweight
    Almost the same size and weight as a hand-held digital multimeter, this calibrator is designed for use in the field.
  • Simple and Easy Calibration
    For the CA11E and CA12E, There is performing calibrations during periodic maintenance as they can be simply calibrated by the up/down keys.
  • Complete Protection (CA11E)
    The complete protector protects the circuit against short-circuiting of the voltage output terminals and application of a voltage (of up to 30 V) to the output terminals, etc. due to misconnection.
  • Dip Switches
