Model UT513: OPERATING MANUAL Table 1. Unpacking Inspection Introduction Uni-Trend Model UT513 insulation resistance tester (hereafter, ìthe Meterî) is a handheld instrument designed primarily to make resistance/ insulation resistance measurement.
Model UT513: OPERATING MANUAL Safety Information This Meter complies with the standards IEC61010 safety measurement requirement: in pollution degree 2, overvoltage category (CAT. III 600V) and double insulation. CAT II: Local level, appliance, PORTABLE EQUIPMENT etc., with smaller transient voltage overvoltages than CAT. III Use the Meter only as specified in this operating manual, otherwise the protection provided by the Meter may be impaired.
Model UT513: OPERATING MANUAL When carrying out insulation measurement, do not contact the circuit under test. Warning Do not use the Meter if it is damaged or metal part is exposed. Look for cracks or missing plastic. Be careful when working above 33V rms, 46.7V ac rms or 70V DC. Such voltages pose a shock hazard. Discharge all loading of circuit under test after measuring high voltage. Do not change battery when the Meter is in wet environment. Place test leads in proper input terminals.
Model UT513: OPERATING MANUAL International Electrical Symbols Battery Indication International symbols on the Meter and in this manual are explained in Table 2. There is a battery indicator shows on the display upper left hand corner. Below Table 3 is the explanation: Table 2. International Electrical Symbols Risk of electric shock Equipment protected by double or reinforced insulation.

Model UT513: OPERATING MANUAL Key Functions ON/OFF E-STOP CLEAR / SAVE 14 Table 7. Key Description Turn on or off the Meter. Press and hold the button for 1 second to turn the Meter on. Press again to turn off the Meter. The Meter default range is 500V insulation resistance continuous measurement when turning on. Emergency stop button. Press this button when the Meter is hang and cannot turn off the power.
Model UT513: OPERATING MANUAL Table 7. Key Description When set the timer duration for the measurement of insulation resistance or polarization index, press to decrement the time. The maximum length of time is 15 minutes and 30 seconds, the Meter will automatically carry out measurement. When compare feature measuring insulation resistance, press to decrement a resistance comparing value.

Model UT513: OPERATING MANUAL Measurement Operation A. Measuring Voltages Below section explains how to make measurements. Press and hold ON/OFF to turn on the Meter, press again to turn off the Meter. The Meter default range is 500V insulation resistance continuous measurement when turning on. Red Green Figure 4.
Model UT513: OPERATING MANUAL Operating Catuion To avoid harms to you or damages to the Meter, please do not attempt to measure voltages higher than 600V or 600V rms, although readings may be obtained. Special care should be taken when measuring high voltage. To measure voltages, set up the Meter as Figure 4 and do the following: 1. Press DCV or ACV button to select DC voltage or AC voltage measurement 2. Insert the red and green test lead into the tested circuit. 3.
Model UT513: OPERATING MANUAL B. Measuring Insulation Resistance Red Green Black Groud Figure 5. Insulation Resistance Measurement Operating Caution When performing insulation resistance tests, remove all power from the circuit to be measured and discharge all the power. Operating the Meter must be very careful as it outputs dangerous voltage during measurement. Must make sure the tested object is firmed clipped, hands are away from the clips, then press TEST button to put high voltage.
Model UT513: OPERATING MANUAL To measure insulation resistance, set up the Meter as Figure 5 and do the following: 1. Press IR button to select insulation resistance measurement. 2. When there is no testing voltage output, press and button to select voltages of 500V, 1000V, 2500V or 5000V. 3. When performing insulation resistance tests, remove all power from the circuit to be measured and discharged all the power. 4.
Model UT513: OPERATING MANUAL Then press and hold TEST button for 2 second to carry out timed measurement. TIME 1 and are displayed and blinked on the LCD on every 0.5 seconds. When the set time is reached, the insulation resistance measurement voltage will be closed and the measurement will be automatically stopped. The LCD displays the insulation resistance reading. Press TIME button to select timed measurement mode, the LCD displays TIME 1 and symbols. Press and buttons to set the time (00:10~15:00).
Model UT513: OPERATING MANUAL Press COMP button to select compare feature. COMP symbol displays on the LCD..
Model UT513: OPERATING MANUAL The Use of Power Adaptor The use of power adaptor, see figure 6 1. Open the side safey shutter, then you will see there is a power adaptor input terminal. 2. Make sure the Meter is power off and insert the UT513 power adaptor to the input terminal. 3. It is highly recommeded to take out all the batteries when you are using the power adaptor. 4. Make sure the Meter is power off when you disconnect the UT513 power adaptor from the Meter. 5.
Model UT513: OPERATING MANUAL USB Interface Connecting the USB interface, see figure 7 Figure 7. USB Interface Connection 24 1. Install the included software, the installation guide can be seen from the CD. 2. Open the side safety shutter, then you will see there is a USB port. 3. Insert the included USB cable to the Meterís USB port and the other end to the computer.
Model UT513: OPERATING MANUAL Maintenance If the Meter is wet, dry it before use. 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.
