UNI-T UT15 Waterproof Type Voltage Tester Instruction Manual

UNI-T UT15 Waterproof Type Voltage Tester

Introduction

Notice:

• Please open the battery cover and remove the anti-leakage piece before using it. (Refer to content 3: instrument layout 13)
• Thank you for purchasing a voltage tester. This tester has been designed in accordance with the latest international safety standards. The combi-volt testers are fully automatic voltage indicators capable of measuring AC/DC voltage up o 690 V. Both units have visual and acoustic continuity indications.
• Constructed in accordance with IEC 61010 and IEC 61243-3.
• Single pole phase indication
• 2 pole phase rotation indication
• LED & LCD display (UT15C)

Safety notices

• This manual contains information that must be followed for operating the meter safely and maintaining the meter in a safe operating condition. if this meter is not used in the manner specified, the protection provided may be impaired.
• Warning! Warns of potential, refer to the instruction manual to avoid personal injury or damage to the meter.
• Caution! Dangerous voltage. The danger of electrical shock
• The perfect display is only guaranteed within a temperature range of – 10~50 C with relative humidity<85%. a Continuous double or reinforced insulation complies with IEC 536, class 11 CE Symbol of conformity, confirms conformity with relevant EU directives. The meter complies with EMC directives (89/336/EEC). Specifically, standards EN 50081-1 and EN 50082-1 as well as the Low Voltage Directive (73/23/EEC) described in the standard EN 61010-1.
• The meter has been designed in accordance with the safety regulations for electronic measuring instruments, EN 61010-1. IEC61010
• Voltages above 75V DC or 50V AC may constitute a serious shock hazard.
• Before using the meter check for physical damage to the casing In particular around the connectors. If the case is damaged do not use the meter.
• Check the test probes for damaged insulation or exposed metal.
• Check the leads for continuity.
• Do not apply more than the rated voltage, as marked on the meter between the terminals or between any terminal and ground.
• Do not use or store the meter in an environment of high temperature, humidity, fumes, vapor, gaseous, inflammable, and strong magnetic field. The performance and safety of the instrument and the user may be compromised in such circumstances.
• Disconnect circuit power and discharge all high-voltage capacitors before testing resistance, continuity, and diodes.
• Remove the batteries if the meter is not in use for a long period.
• Constantly check the battery as may have leaked. A leaking battery will damage the meter.
• The meter may only be opened by a qualified service technician for calibration and repair

Carrying out measurements

• Perform a self-test of the unit. Connect the two test probes L1 and L2.
• The continuity LED (6) will be lit and an audible tone should be heard.
• Before any test check the unit on a known voltage source.
• If the unit is defective it should be put out of service and returned to uni-trend for repair.

Voltage test

• Always hold the test probes by the handles behind the finger guards. Observe the safety notices at all times.
• An audible tone is present when an AC voltage and a negative DC voltage are indicated.
• The maximum switch-on time is 30 s. When this time has elapsed you must wait 10 minutes before retesting.
• Connect probes to voltage source observing the polarity of the test probes L2 is a positive probe, and L1 is the negative probe.
• For AC voltage the value is indicated on the LEDs (3) and on the LCD display ( UT15C only). The + and – LEDs are illuminated and the buzzer is audible.
• For DC voltage connect probe L2 to the positive terminal and L1 to the negative terminal. The voltage is displayed on the LEDs and the LCD display ( UT15C only ). The positive LED (10) is illuminated. If the polarity is reversed the buzzer will sound. The negative LED (11) will be illuminated.

Single pole voltage detection

• Perform a function test prior to this test.
• This unit can be used as a single-pole voltage detector when batteries are inserted.
• The single pole test is intended only as a quick check. The the circuit must be checked again for the presence of voltage using the two-pole method.
• Connect test probe L2 to the voltage source and keep a finger on the contact electrode (8). If an AC voltage above 100 V is present the LED (4) is illuminated and the buzzer sounds.
• The single pole test can be negatively affected by favor- able conditions such as electrostatic field, good insulation, etc.

Continuity test

• The continuity test is only possible when batteries are inserted and in good condition.
• Ensure the circuit under test is not live.
• Connect test probes L1 and L2 to the circuit.
• The continuity LED (6) will illuminate and the buzzer will sound.
• The unit indicates continuity below 400 Kohm

Phase rotation test

• Perform a function test prior to this test.
• This unit can determine the phase rotation within a three-phase supply.
• Connect test probe L2 to the supposed phase 2 and test probe L1 to the supposed phase 1. If the R LED illuminates the phases are in the correct sequence 1 to 2.
• Connect test probe L2 to the supposed phase 3 and test probe L1 to the supposed phase 2. If the R LED illuminates the phases are in the correct sequence 2 to 3.
• Connect test probe L2 to the supposed phase and test probe L1 to the supposed phase 3.
• If the R LED illuminates the phases are in the correct sequence 3 to 1.
• During phase rotation test touch the contact electrode.
• If the L LED illuminates then the phase sequence is anti-clockwise.

Maintenance

• Do not attempt to repair this unit. There are no user-serviceable items n this unit. Never attempt to open the casing apart from the battery cover.
• Do not use the instrument if there is any physical damage to the case or test leads. of The outside of the unit can be cleaned with a soft damp cloth only. Do not use abrasive or chemical cleaning agents.

Changing batteries

• Turn the battery cover by 90 degrees anti-clockwise. Remove the cover and take out the spent batteries. Replace with 2 off 1.5V AAA (LR03) batteries, checking the correct polarity.

Calibration

• The recommended calibration interval for the UT15A/UT15B/UT15C is 12 months.
