VT30

User's Guide LCD Multifunction Voltage Tester Model VT30 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 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. 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 VAC, VDC, Continuity Low Impedance 2. 3. 4. 5. Input Protection Limits Maximum Input 480VAC, 690VDC 3s
