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
closed calibrator.
Introduction
Volt/mA Calibrator is a source and measurement tool. This Calibrator is use to measure or output
0 to 24 mA DC current loop, and 0 to 15 DC voltage. But the calibrator cannot be used to
measurement and source simultaneously.
Volt/mA Calibrator include this accessories: Holster, a pair of Test Leads, AAA*6 battery, and this
manual.
If the calibrator is broken or short of some accessories, please contact the supplier. Please contact
the distributor about other accessory’s information.
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 if 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 battery.
Replacing a Fuse
Warning!
To avoid personal injury or da age to the calibrator, use only a 0.125A 250V Fast fuse.
Fuse 1 is probably blown if:
In the V output mode, with the test leads removed from the calibrator, the display flashes OL.
Fuse 2: is probably blown if:
In the mA mode, the calibrator always reads 0.000, even with a signal applied.
