LC-100 PRECISION LOOP CALIBRATOR
|
 |
|
 |
 |
The Martel Electronics LC-100 Precision
Loop Calibrator provides significantly extended performance
when compared to any competitive calibrator. With an
accuracy of 0.015% of reading, with 0.001 mA resolution, the
LC-100 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, put the
LC-100 way beyond similar instruments. The Martel LC-100 can
simulate, power, and measure two-wire transmitters. With
automatic Step and Ramp functions, the LC-100 enables remote
calibration of 4-20mA devices.
General Features
- Very high accuracy - ±0.015% of
reading
- Very high resolution -
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 28.000 VDC
- Built in 250 Ohm resistor
facilitates calibration of HART devices
- Remote calibrations through
Automatic Step and Ramp functions
- Loop power measurements capability
- Simulates, powers, and measures
two-wire transmitters
- Five preset outputs (4, 8, 12, 16,
20 mA)
- Fuseless input protection up to
250 VAC
- Supplied in full rubber boot;
optional carrying case available

IVC-222HPII PRECISION VOLTAGE/CURRENT CALIBRATOR
|
|
|
 |
|
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 application. It
combines both digital and analog circuitry to achieve its
rated specifications in a small, reliable package.
The IVC-222HPII has the capability to store and recall 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.
General Features
- Remarkable 0.015% of reading
accuracy
- Four ranges: 200 mV, 2V, 20V, and
24 mA
- Intuitive, easy-to-use controls
- RS-232 interface 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 certificate
- Full rubber boot with optional
carrying case.

SOURCE PORTABLE CALIBRATOR
|
|
|
|
|
|
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 9V battery, NIST Certificate,
and instruction manual.
