The CA71 Portable Calibrator is a small, lightweight, multifunction calibrator by Yokogawa that can simultaneously source and measure voltage, current, resistance, TC, RTD, frequency, and pulse signals with high accuracy. The Handy Calibrator incorporates rotary switches for simple handling. Just open the carrying case cover and connect the cables, and you're ready to take measurements. The Handy Calibrator incorporates rotary switches for simple handling.

Features:

• Divided output (n/m) function, Auto-step function, Sweep function, Memory function and Communication function
• Generate voltage/current up to 30 V DC/24 mA DC and measure up to 100 V DC/100 mA DC
• Can be used as a multi thermometer
• Built-in reference junction compensation sensor
• Frequency can be set in the range of 1 Hz to 11 kHz

Technical Data:

Auto-Step Output Function	n value sent automatically when n/m function selection is selected (two options: approximately 2.5 seconds/step or approximately 5 seconds/step)
Sweep Functions	Sweep time (two options: approximately 16 seconds or approximately 32 seconds)
Memory Function	50 value sets (generated and measured values are stored as value sets with the same address (up to 50 value sets can be stored))
Measurement Display Updating Rate	Approximately once per second
Serial Interface	Enabled when communication cable (RS232) is connected; sold separately as optional accessory
Backlight	LED backlight; auto-off after one minute (from when LIGHT key is turned on)
Power Supply	Four AA alkaline batteries, or special AC adapter (sold separately)
Battery Life	Measurement off, output 5 V DC/10 kO or greater: Approximately 40 hours Simultaneous signal generation/measurement, output 5 V DC/10 kO or greater: Approximately 20 hoursSimultaneous signal generation/measurement, output 20 mA/5 V: Approximately 12 hours (using alkaline batteries, with backlight off)
Applicable Standard	EN55011: 1998, Class B, Group 1 EN61326-1: 1997 + A1: 1998 IEC61010-1, IEC61010-2-31
Insulation Resistance	Across input terminal and output terminal, 500 V DC, 50 MO or greater
Withstand Voltage	Across input terminal and output terminal, 3.7 kVAC, for one minute

A Wide Array of Useful Functions:

• Source: Values set in steps of 4-20 mA 24V DC Power Supply to Transmitter
• Divided output (n/m) function: Output settings are divided, eliminating the need for bothersome calculations for percentage output.
• Autostep function: Changes the output value in step form based on the setting from the divided output (n/m) function. Changes can be sourced automatically every 10% or 25%.
• Online communication (CA71 only) RS-232C-compliant optically isolated interface
• Sweep function: Linearly increases or decrease the output. The increasing/decreasing time can be set to either 16 or 32 seconds.
• Memory function: Source values and measurements forming individual value sets can be saved to or read from the Handy Calibrator's internal memory (maximum 50 value sets).
• Temperature monitor function

Exemption from Responsibility

Software Features: 

• The communication function of CA71 Communication Software enables users to set output values of the CA71 on a PC. However, the range for generation/measurement should be selected using the rotary switch on the calibrator.
• The following operations can be executed while monitoring the CA71 on the PC.

Data Receiving	Memory-mode data or real-time data can be received from the CA71.
Data Transmission	Setting value of generation can be set and sent to the CA71.
Data Processing	The data can be saved and forwarded to EXCEL. A trend graph is created and shown on the PC screen.
