Model UT512: OPERATING MANUAL Introduction Uni-Trend Model UT512 insulation resistance tester (hereafter, “the Meter”) is a handheld instrument designed primarily to make resistance/ insulation resistance measurement. Unpacking the Meter The Meter includes the following items: Table 1.
Model UT512: OPERATING MANUAL Conforms to Standards of European Union Battery Saver (Sleep Mode) The Meter enters the Sleep Mode and blanks the display if there is no button press for 15 minutes. This is done to conserve battery power. The Meter comes out of Sleep Mode when ON/OFF button is pressed and hold for 1 second. Battery Indication There is a battery indicator shows on the display upper left hand corner. Below Table 3 is the explanation: Table 3.
Model UT512: OPERATING MANUAL Press again to exit Load feature. Load feature can only be used when there is no high voltage output. When the insulation resistance measurement has no testing voltage output, press to select one voltage range up. Under load mode: press to recall the previous stored value. When the insulation resistance measurement has no testing voltage output, press to select one voltage range down. Under load mode: press to recall the next stored value.
Model UT512: OPERATING MANUAL Press and hold TEST button for 1 second to carry out continuous measurement. Output insulation resistance testing voltage, TEST button light up, blinks on every 0.5 seconds. Press TEST button to close the insulation resistance measurement voltage when measurement is completed. TEST button lights off, disappears. The LCD shows the current insulation resistance measurement value.
Model UT512: OPERATING MANUAL Maintenance This section provides basic maintenance information including battery replacement instruction. Warning Do not attempt to repair or service your Meter unless you are qualified to do so and have the relevant calibration, performance test, and service information. A. General Service Periodically wipe the case with a damp cloth and mild detergent. Do not use abrasives or solvents.
