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 mA

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.

Temperature Calibrator

Features

Simulator of Common Thermocouples and RTD Sensors

Outputs a signal equivalent to signals of ten types of thermocouple K, E,
J, T, N, S, B, L, M and R as well as Pt100 resistance temperature detector.

Suitable for a broad range of applications such as maintenance of industrial
process instruments and various thermometers.

Multi-range Thermometer

Can be used as a multi-range thermometer. Three-wire RTD connection for an
RTD is possible.

Built-in Sensor for Reference
Junction Compensation

Reference junction compensation when generating a thermocouple signal can
be performed by the built-in temperature sensor. For more precise
compensation, use the external RJC sensor (model B9108WA, sold separately).

Shift Key

”

Terminal Adapter

Provides screw terminals for connecting a temperature sensor such as a
thermocouple and RTD when measuring temperature. When generating an
RTD signal, a three-wire RTD signal can be output using the lead cables that
come with the CA12E by short-circuiting the Lo-Lo terminals using the short­circuit bar that also comes with the CA12E.

Examples of Applications

4-20mA

CA11E

This is an example of
connecting the CA11E to a
two-wire transmitter.

HiLo

The CA11E can generate a
voltage of up to 24 V and
current of up to 22 mA. It can
operate the two-wire
transmitter to output and
measure 4-20 mA.

Temperature controller

or converter

This is an example of connecting
the CA12E to a receiver
instrument for a three-wire
resistance temperature detector
(RTD). Using the PT100 range,
the RTD signal equivalent to the
temperature set at the CA12E is
output to the receiver instrument.
To cancel the lead wire resistance,
connection using three wires is
necessary. The terminal adapter
that comes with the CA12E
simplifies this three-wire
connection.

(Distributor)

This is an example of
connecting the CA11E to a
distributor for two-wire
transmitters. The CA11E can
absorb up to 28 V DC
supplied from the distributor
and generates a 4-20 mA
output (using the 20-mA SINK
range), allowing loop check.

(Generation)

CA12E

External RJ

-

Temperature controller

Temperature converter etc.

The CA12E can generate a
thermo-electromotive force
suitable for ten kinds of
thermo-coupler. By attaching
an external RJ sensor to the
thermocouple to be calibrated,
thermo-electromotive force
can be output after
temperature difference of the
thermocouples is corrected.

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.)

Rubber boot (93038) Strap (97040)

Allows the calibrator
to be hung on a wall.

Automatic Power-off

Power is turned off automatically if the calibrator is not touched for 10
minutes, prolonging battery life.

Accessory case

(B9108XA)

Used to store probes
and accessories.

For the CA11E and CA12E, There is performing calibrations during
periodic maintenance as they can be simply calibrated by the

Simple and Easy Calibration

up/down keys.

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).

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.

The roomy case easily
holds the calibrator without
having to disconnect the
lead cables.

carrying case

(B9108NK)

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.
