This is a general purpose current and voltage source that can  be used in engineering, manufacturing, test, and process control applications. It combines both digital and analog circuitry to achieve its rated specifications in a small, reliable package.

It has the capability to store an drecall up to two setpoint values, the SP1 and SP2 keys. An RS-232 port accessed via a custom cable (available from Martel) allows the calibrator to be computer controlled for automated testing.

Features:

• Remarkable 0.015% of reading accuracy
• Four Ranges: 200 mV, 2V, 20"V, and 24mA
• Intuitive, easy to use controls
• RS232 interfacw allows computer control
• Built-in 24V supply can drive 4 to 20 mA loops over 1,000 Ohms
• Rugged, lightweight, hand-held unit
• Includes test leads, carrying case, 9V battery, NIST
• Full rubber boot with optional carying case. Certificate, and instruction manual included.
