Caution---identifies conditions and actions that will pose hazard(s) or damage the tester. Danger ● This test instrument unit is suitable for using under single phase 230V+10%-15%.
UT581/582 INSTRUCTION MANUAL ● Do not use your finger to touch on any testing cable during the testing stage. ● Put off the test leads after testing complete. P.S. test leads can not always plugs on the test instrument. Warning ● Do not open or disassemble the tester un-intentionally during the measurement, it has a high voltage inside and cause a danger for the user. If it needs service repairing, please contact our after-sales services or our agents.
UT581/582 INSTRUCTION MANUAL Caution ● Ensure the test lead probe (need to be provided by UNI-TREND Certified One) insert into the corresponding port in order to provide a safe before measurement. It is not encourage to use third parties test lead probe on our tester. ● Do not expose the tester in extreme temperature and wet environment. ● Soft cloth and mild detergent should be used to clean the surface of the tester. No abrasive and solvent should be used when servicing.
UT581/582 INSTRUCTION MANUAL 2. Characteristics 2.0 This tester is suitable for using under single phase 230 V / 50 Hz. (Operational Voltage Scope: 195 – 253 V) 2.1 It uses micro-controller with high accuracy, reliability and satiability. 2.2 Connectivity Checking: 3-LED Lamp signal is correct or not . Correct connectivity: P-E & P-N display two green light signal on but red light is off, If not, you may incorrect to connect it. 2.

UT581/582 INSTRUCTION MANUAL 5. Measurements 5.1 Test Lead Connection Test terminal is / are for connecting the correct lead of the tested installation: L to L(Live); N to N(Neutral); E to E(Earthing). 5.2 Test Lead Checking After connected the test leads with the testers, please plug the power cable on (220V/50Hz current socket), so you can 3-LED lamp whether it is correct. If P-E & P-N are displayed green signal light, but the red color LED do not light up. It is in good normal condition.
UT581/582 INSTRUCTION MANUAL Danger ● If the connecting measurement is incorrect, please don’t proceed the next measurement (press TEST button). Otherwise, it causes measuring result incorrect or in other dangerous. 5.3 Press I△n button switch, it causes RCD breakers for the nominal residual currents (I△n) as the previous trip current in constant Below LCD display the default connecting current value. Default Value: I△n 30mA 0°/180° 0° 5.4 Measuring Methods 5.4.
UT581/582 INSTRUCTION MANUAL • Rapid Connecting Test ×5 (10,20,30mA only): Maximum Measuring Time 1000ms • Rapid Connecting Test 250 mA: Maximum Measuring Time1000ms(UT581 only) • AUTO RAMP TEST Auto Ramp Test(UT582 only). 20%~110% Default nominal residual currents(I△n).
