Introduction
Congratulations on your purchase of the Extech VT30 Multifunction Voltage Tester. The VT30 measures AC voltage to 480V and DC Voltage to 690V with LCD readout, stepped voltage bargraph indicator, and LEDs for positive and negative polarity. Additional features include audible continuity beeper, low impedance test 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 Precautions
1. Improper use of this meter can cause damage, shock, injury or death. Read and understand this manual before use.
2. Ensure that any covers or battery doors are properly closed and secured before use.
3. Inspect the condition of the test leads and the meter itself for any damage before use.
4. Do not exceed the rated input limits.
5. Use great care when taking measurements greater than 25VAC rms or 35VDC. These voltages are considered a shock hazard.
6. Discharge capacitors and remove power from the DUT before Continuity tests.
7. Remove the batteries from the meter if the meter is to be stored for long periods.
8. Voltage measurement results on electrical outlets can be misleading because of the difficulty in making a proper connection to the electrical contacts.
Safety Instructions
This meter has been designed for safe use, but must be operated with caution. The rules listed below must be carefully followed for safe operation.
1. NEVER apply voltage to the meter that exceeds the specified maximum:
Function Maximum Input VAC, VDC, Continuity 480VAC, 690VDC Low Impedance 3s<400V AC/690V DC
2. USE EXTREME CAUTION when working with high voltages.
3. ALWAYS discharge filter capacitors in power supplies and disconnect the power when
making continuity tests.
4. ALWAYS disconnect the test leads before opening the cover to replace the battery.
5. NEVER operate the meter unless the battery cover is in place and fastened securely.
