Safety Infor ation
To avoid possible electric shock or personal injury:
•Never apply more than 30V between any two jacks, or between any jack and earth ground.
•ake sure the battery door is closed and latched before you operate the calibrator.
•Remove test leads from the calibrator before you open the battery door.
•Do not operate calibrator if it is damaged.
•Do not operate the calibrator around explosive gas, vapor, or dust.
To avoid possible damage the calibrator:
•ake sure choose the right jack and rang, before use the calibrator to measurement or calibrator.
•Take away the calibrator from the used circumstance, before operate the calibrator or after close
the calibrator.
Introduction
RTD Process Calibrator is exactitude measurement and source instrument, it can be use to calibrate
the RTD
*
transmitter (include most impulse transmitter).
RTD Process Calibrator can measure or simulate 7 difference types of RTD (
o
C or
o
F) and measure
or simulate the Resistance. But it could not use to measurement or source at a same time.
The accessories: 2 pair of test lead and alligator clip, 6 *AAA 1.5V battery, user’s manual.
If the Calibrator is broken or short of some accessories, please contact the supplier.
The following table has showed the technical parameter and function of the Calibrator.

Maintenance
Cleaning
Periodically wipe the case with a damp cloth and detergent; do not use abrasives or solvents.
Calibration
Calibrate your calibrator once a year to ensure that it performs according to its specifications.
Replacing the Battery
Please change the battery when the LCD indicates .
Turn off the power of the Calibrator, when you change the battery, and screw off the breechblock
on the battery cabinet cover, then take off it and instead the fresh AAA 1.5.V battery.
