Current Loop Calibrator
Martel LC-100 Current Loop Calibrator - 4-20 mA Current Calibrator
Loop Calibrator Features:
- High accuracy of ±0.015%
- High resolution of 0.001mA/0.001V
- % Error Function eliminates manual error calculation
- Extended Adjustment Range - digital knob and user-selectable decade output allow both large and incremental (0.001 mA step) output changes
- Reads 0 to 28.0 VDC
- Built-in 250 Ohm Resistor facilitates calibration of HART Devices
- Automatic Step and Ramp functions allow for Remote Calibrations
- Loop Power Measurements
- Simulates, Powers, and Measures Two-Wire Transmitters
- Five Push button Preset Outputs (4, 8, 12, 16, 20 mA)
- Fuseless Input Protection up to 250 VAC
- Includes neoprene sleve, NIST Certificate with calibration data
The Current Loop Calibrator provides significantly extended performance when compared to any competitive current calibrator. With an accuracy of 0.015% and a 0.001 mA resolution, the 4-20 ma calibrator has the highest accuracy in its class. Unique features, such as a "% Error" function, which eliminates manual error calculation and allows the display of the actual versus ideal error at any calibration point, puts this current calibrator way beyond similar
instruments. The loop calibrator can simulate, power, and measure two-wire transmitters. With automatic Step and Ramp functions, the precision loop calibrator also enables remote calibration of 4-20mA devices.

Loop Calibrator
MS-420 Loop Calibrator - Mini-source Portable Loop Calibrator
Loop Calibrator Features:
- Calibrates Chart Recorders
- Calibrates Panel Meters
- Calibrates Data Acquisition Devices
- Calibrates Other Process Instruments
The Loop 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 9V battery, NIST Certificate, and instruction manual.

Voltage Current Calibrators
IVC-222HPII Voltage Current Calibrator - Precision voltage/current calibrator
Voltage Current Calibrator Features:
- Remarkable 0.015% of reading accuracy
- Four ranges: 200 mV, 2V, 20V, and 24 mA (source only)
- Intuitive, easy-to-use controls
- RS-232 interface allows computer control
- Built-in 24V power supply can drive 4 to 20 mA loops over 1,000 Ohms
- Rugged, lightweight, hand-held unit
- Includes test leads, 9V battery, NIST certificate with data calibration
- Neoprene sleeve, optional carrying case available
The 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 specifications in a small, reliable package.
This voltage current calibrator has the capability to store and recall up to 2 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.
