Voltage Calibrator- Current Calibrator

Signal source: DCV (Max. 30V), DCA (Max. 24 mA)
Measurement: DCV (Max. 30V), DCA (Max. 100 mA)
Features: Auto step (4 to 20mA), 20mA SINK, Sweep function
Options: CA11E-2 Includes rubber boot, strap and accessory case

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.

Standard Accessories
Carrying Case

By four-digit up/down keys

Response of Generator
Approx. 1 second (from when the output begins to change until when the output level falls within the specified accuracy)

Approx. 1 update/sec.

Update interval Display
7 segments LCD

Operating Temperature/Humidity Range
0 to 50°C and 20 to 85%RH (no condensation)

Storage Temperature/Humidity Range
-20 to 50°C and 90%RH or less (no condensation)

Additional Features
Complete Protection (CA11E) Dip Switches (inside battery compartment) Longer Lead Cables Rubber Boot Runs on 1.5 V AA-size Batteries or AC Adapter Simple and Easy Calibration

Additional Features

Choose either “rubber boot” or “carrying case” Rubber boot, strap and accessory case can be chosen as standard accessories to improve impact resistance and make it easier to carry. (The calibrator cannot be stored in the carrying case when the rubber boot is attached.) The roomy case easily holds the calibrator without having to disconnect the lead cables.
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.

Panel Designs Common to Both Models

Power Switch
Up/Down Keys Used to set the output signal level. A pair of up/down keys is conveniently located immediately below each digit in the LCD panel.
Output On/Off Switch (Output signal can set ON/OFF)
Range Selection Rotary Switch The rotary switch simplifies range selection: just leave the switch set to the most frequently used range.
