User's Guide Multifunction Voltage Tester Model VT10 Introduction Congratulations on your purchase of the Extech VT10 Multifunction Voltage Tester. The VT10 measures AC Voltage to 600V and DC Voltage to 400V with LED indicators, and LEDs for positive and negative polarity. Additional features include audible continuity beeper, low impedance mode for eliminating phantom voltages, and a built-in flashlight to illuminate test connections during measurements. This meter is shipped fully tested and with proper use will provide years of reliable service. Safety International Safety Symbols This symbol, adjacent to another symbol or terminal, indicates the user must refer to the manual for further information. This symbol, adjacent to a terminal, indicates that, under normal use, hazardous voltages may be present Double insulation Safety Precautions 1. 2. 3. 4. 5. 6. 7. 8. 9. Improper use of this meter can cause damage, shock, injury or death. Read and understand this manual before use. Ensure that any covers or battery doors are properly closed and secured before use. Inspect the condition of the test leads and the meter itself for any damage before use. Do not exceed the rated input limits. Use great care when taking measurements greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard. Discharge capacitors and remove power from the DUT before Continuity tests. Remove the batteries from the meter if the meter is to be stored for long periods. Voltage measurement results on electrical outlets can be misleading because of the difficulty in making a proper connection to the electrical contacts. NEVER apply voltage to the meter that exceeds the specified maximum: Function VAC, VDC, Continuity 10. 11. 12. 13. Input Protection Limits Maximum Input 600VAC: 30 second max 400VDC: 30 second max USE EXTREME CAUTION when working with high voltages. ALWAYS discharge filter capacitors in power supplies and disconnect the power when making continuity tests. ALWAYS disconnect the test leads before opening the cover to replace the battery. NEVER operate the meter unless the battery cover is in place and fastened securely. 2 VT10 V2.0 08/06 Warranty EXTECH INSTRUMENTS CORPORATION warrants this instrument to be free of defects in parts and workmanship for one year from date of shipment (a six month limited warranty applies on sensors and cables). If it should become necessary to return the instrument for service during or beyond the warranty period, contact the Customer Service Department at (781) 890-7440 ext. 210 for authorization or visit our website at www.extech.com for contact information. A Return Authorization (RA) number must be issued before any product is returned to Extech. The sender is responsible for shipping charges, freight, insurance and proper packaging to prevent damage in transit. This warranty does not apply to defects resulting from action of the user such as misuse, improper wiring, operation outside of specification, improper maintenance or repair, or unauthorized modification. Extech specifically disclaims any implied warranties or merchantability or fitness for a specific purpose and will not be liable for any direct, indirect, incidental or consequential damages. Extech's total liability is limited to repair or replacement of the product. The warranty set forth above is inclusive and no other warranty, whether written or oral, is expressed or implied.

Note: The voltage tester will turn on automatically when voltages higher than 4.5V AC/DC are detected. 2. Touch the positive (+) and negative (-) test leads to the device or circuit under test. 3. If the voltage is higher than 4.5V AC/DC, the voltage level LEDs will light and display the reading. For AC voltages, the LED and the “AC” LED will light in the display. For DC voltages, the “DC” LED will light and the “+V” or “-V“ LED will light to indicate polarity. Note: The measurement time should not exceed 30 seconds. After 30 seconds the meter should be allowed to cool for 10 minutes. 4. Single Lead AC Voltage Detection To check for the presence of voltage (between 100V and 600V) using only the positive test lead (+), touch the lead to the device or circuit under test. If voltage is present, the LEDs will light. Note: In this mode, the actual voltage is not displayed; only the presence of voltage is detected. Low Impedance Voltage Measurement Due to the lowered internal impedance, capacitive voltage is suppressed so that the reading shows the actual voltage applied. This can be used to quickly identify phantom voltages. 1. 2. 3. Hold the two test tips on the measuring points to be tested. Press the two low impedance test buttons simultaneously. The Low Impedance LED will light and the applied voltage will be displayed on the LEDs. Note: The maximum duty cycle in this mode is 5 seconds for voltages up to 250V. Allow 10 minutes between each reading. Note: Measuring from hot to ground may trip any GFCI equipped circuits. Continuity Test The tester can measure resistance and alert the user if the resistance value is less than 400kΩ. 1. Before taking a continuity test, make sure that power to the device or circuit under test is off and that all capacitors are discharged. 2. Touch the test tips to the device under test. 3. If the resistance is less than 400kΩ., the tester will sound an audible alert and the continuity LED will light. Flashlight Press and hold the button to turn the flashlight on. Release the button to turn the flashlight off. 4 VT10 V2.0 08/06 Maintenance Battery replacement 1. Disconnect the meter from any test device or circuit before opening the tester. 2. Loosen the recessed Phillips head screw at the bottom of the tester. Do not remove the screw. 3. Hold the meter and pull the lower portion of the meter off until the batteries are exposed. 4. Replace the two ‘AAA’ batteries observing polarity and dispose of the old batteries properly. 5. Slide the meter back together and replace the screw. Cleaning and Storage Before cleaning the tester, ensure that the test leads are not connected to any circuit or device. Wipe the meter only with a damp cloth as needed. Do not apply abrasives, solvents, or other cleaners to the surface of the meter. Store with the battery removed and avoid extreme temperature and humidity.
