Martel PTC-9002
Temperature Calibrator

The Martel PTC-9002 is a full function thermocouple/RTD
calibrator combined with the ability to simultaneously read and
display a 4 to 20mA current loop. These features make it ideal
for calibrating all types of temperature measureing devices and
transmitters. Housed in a rugged hand-held case, the PTC-9002
features 0.5°C accuracy on the most commonly used T/C and
RTD ranges. Up to nine (9) setpoints can be stored in non-volatile
memory for each of the seven ranges. An auto-step function
allows the user to automatically step through each of the stored
setpoints for a particular range at a predetermined interval. Resolution
is .1°C/.1°F on all temperature ranges and .001mA on the milliamp
range. An internal 24 volt loop power supply allows the user to
power a two-wire transmitter and read the output current.
No external loop power is required.

FEATURES

• High Accuracy on 4 T/C and 3 RTD Ranges
• Direct Keyboard Entry of Data
• 63 Point Calibration Memory
• Simultaneous Display of Temperature Output
and 4-20mA Input
• Built-in 24 Volt Loop Power Supply
