The Martel Electronics IVC-222HPII Voltage/Current
Calibrator 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 specifcations in a
small, reliable package.

The IVC-222HPII has the capability to store and recall up
to two setpoint values using 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.

MS-420
Mini-Source Portable Calibrator

Typical Applications:

Chart recorder
Panel meter
Data acquisition
Other process

instruments

The Martel Electronics MS-420 Mini-Source Portable
Calibrator is a multi-purpose process loop tool that offers

high accuracy in an ultra-small, rugged package.

A single pushbutton selects one of five current outputs
(4, 8, 12, 16, or 20 mA), which can drive up to 300 Ohms,
or can act as a 2-wire simulator with an external loop
power supply of up to 30 VDC.

Each unit is provided with a 9 V batery, NIST Certificate,
and instruction manual.
