Introduction

The Uni-Trend UT712 Volt/mA Calibrator is a source and measurement tool for 0 to

20mA current loop testing and DC Voltage from 0 to 20V. The calibrator does not

source and measure simultaneously.

Your calibrator has a unique design and large LCD can read the data clearly.

Your calibrator is supplied with the following:

User Manual

Safety Information

Use the calibrator only as specified in this user manual, otherwise the protection

provided by the calibrator may be impaired.

A Warning identified conditions and actions that pose hazard(s) to her user.

Model UT712: OPERATING MANUAL

Warning

To avoid possible electric shock or personal injury:

Never apply more than 30V between any two jacks (terminals), or between

any jack and earth ground.

Make sure the battery door is closed before you operate the calibrator.

Remove test leads from the calibrator before you open the battery door.

Do not operate calibrator if it is damged.

Do not use or store the calibrator in an environment of high temperature,

humidity, explosive, inflammable and strong magnetic field. The performance

of the Meter may deteriorate after dampened.

When servicing the calibrator, use only specified replacement parts.

Use the proper jacks, function, and range for your measurementt or output

application.

To avoid false readings, which could lead to possible electric shock or

personal injury, replace the battery as soon as the battery indicator ( )

appears.

Turn the calibrator off when it is not in use and take out the battery when

not using for a long time.

Model UT712: OPERATING MANUAL

Constantly check the battery as it may leak when it has not been using for

some time, replace the battery as soon as leaking appears. A leaking

battery will damage the calibrator.

The internal circuit of the calibrator shall not be altered at will to avoid

damage of the calibrator and any acccident.

When the calibator is off, the jacks cannot connect to any loading or they

must not be short circuit between jacks.

When the calibrator is carrying out measurment, do not contact any bare

cable, connector, used jacks or the circuit under test.
