A great balance of performance and value for the benchtop calibration of process instrumentation

The Martel 3001 multi-function precision bench calibrator provides the power and features of calibrators costing thousands more. It combines the simulation and measurement of voltage, current, thermocouple, RTD and pressure with a second completely isolated measurement channel for an instrument unmatched in versatility, performance, and value. The 3001’s world-class performance and features are accessed through a very simple-to-use, intuitive user interface.

Simple, Intuitive Interface

The 3001 provides simple, front-panel entry of mode, range, and value, using either direct key-board entry or cursor entry. Using cursor entry , the LEFT/RIGHT arrow keys are used to move the cursor under the digit in the display to be changed. The UP/DOWN arrow keys increment/decrement the value at the cursor position. Using direct keyboard entry, the exact value desired is entered using the numeric keys, and the ENTER key is pressed to set the output to that value. Whichever way you choose, setup is simple and fast. In the voltage output mode, the 3001 auto-ranges on the entered value for maximum accuracy at all times.
The Performance You Demand In Any Mode
Voltage Mode The 3001 offers four precision voltage output ranges (100 mV, 1 V, 10 V, and 100 V) all with 30 ppm accuracy. These ranges are ideal for calibrating a broad range of DC voltage instrumentation. Additionally all voltage outputs settle to full specification in less than 200 ms making the 3001 ideal for automated calibration systems. An automatic stand-by mode assures that output voltages above 30 VDC must be acknowledged by the operator before the voltage appears at the output jacks. The stand-by mode is also triggered if the output current compliance is exceeded, thereby protecting the device under calibration.

Current Mode

The 3001 features a precision 100 mA current output range that offers 100 ppm accuracy that is ideal for calibrating 4 to 20 mA process instrumentation. With a full 12 volts of compliance at 100mA virtually any precision DC current measuring device can be calibrated using the 3001. Like the voltage ranges the current range offers quick settling time and an operate/standby mode.

Thermocouple Mode

The Martel 3001 can read and source any of 11 types of thermocouples. Its T/C input and output is Cold Junction Compensated, using an ultra-stable PT-1000 sensor.

RTD Mode

The 3001 can read and source 9 RTD types as well as YSI-400 and Ohms for non-standard curves. Callendar Van Dusen probe coefficients (A, B, C, and R0) can be entered directly, with storage for up to five custom curves and one SPRT curve. The performance of the 3001 in the RTD mode is comparable to dedicated RTD measurement instruments. Unlike low-cost, less accurate RTD instruments, the display in the 3001 is always active, reading to three decimal places, using polynomial averaging to extract a high accuracy signal. The result is a very quiet, high accuracy reading.

Pressure Mode

The 3001 operates with all Martel BetaPort series and Fluke 700P series pressure modules and covers pressure ranges from 0 to 10″ H2O to 10,000 psi. Pressure can be displayed in a wide range of engineering units with up to 0.025% Full Scale accuracy.
