1.Calibrates a transmitter using the split-screen 2.Manual stepping and automatic stepping and ramping 3.Super-strong protect Function

1 )A split-screen display. The upper display allows you to measure volts, current (with loop power), resistance and continuity test. The lower display allows you to measure and source volts, current, resistance temperature detectors (RTD), thermocouples (TC), frequency, and ohms.

2) Calibrates a transmitter using the split-screen.

3) The measure of thermocouple provides automatic reference junction.

4)Automatic and manual cold end temperature compensation for TC.

5) Manual stepping and automatic stepping and ramping.

6)Super-strong protection:The waterproof grade is IP67. Automatic protection against the signal terminals connect to the 220V.

Warning 

To avoid possible electric shock or personal injury:

1) Test a given voltage to confirm its normal operation before using. Mutual authentication of the upper and lower display data, for instance.

2)Please follow all the safety operation procedures.

3)Select the proper function and range gear according to measurement requirements.

4) Confirm that the battery door has been closed before application.

5)Remove the test line of the calibrator before opening the battery door.

6)Check whether damaged or exposed metal exists in test line and whether the test line has been conducted. Replace the damaged test line before using.

7)Do not touch the metal contact when the detector is used.

8) Connect the common line and then electric test line. As for wire removal, electric test line should be removed first.

9)Don't use the calibrator under any abnormal conditions. Calibrator should be repaired because it may have been damaged.

10) Don’t use the calibrator near explosive gases.

11) Remove test line before changing measurement or output function.

12) 6 LR03-model (size 7) alkaline batteries or R03-model nickel-metal hydride batteries (or nickel-cadmium batteries) should be used in the calibrator and the battery should be placed inside the meter housing.

13) To avoid reading error and possible electric shock or personal injury when the screen displays the battery under-voltage, please replace or charge the battery.
