DO NOT UNDER ANY CIRCUMSTANCES EXCEED THESE RATINGS: - Voltage is not to exceed 800 Volts. - Wattage, Resistance and Continuity functions are not to be performed on circuits capable of delivering greater than 600 Volts. - Current measurements are not to be performed on circuits capable of delivering greater than 500 Volts 2. To avoid electrical shock hazards and/or damage to the meter: - Do not exceed the voltage ratings for the meter. Use caution when measuring voltage. - Do not use during electrical storms. AC power sources with inductive loads or electrical storms may result in high voltage. High energy transients can damage meter and present a dangerous shock hazard. - Turn off power to the circuit or device being measured before taking resistance and capacitance measurements. Fully discharge all capacitors before measuring. 3. Ensure meter is in proper working order before using. Visually inspect meter for damage. Performing a continuity check can verify proper operation. If the meter reading goes from overload to zero, this typically means the meter is in proper working order. 4. Visually inspect leads for damage before using. Replace if insulation is damaged or leads appear suspect. 5. Never ground yourself when taking electrical measurements. Do not touch exposed metal pipes, outlets, fixtures etc. Keep your body isolated from ground by using dry clothing, rubber shoes, mats, or any other approved insulating material. Keep your fingers behind the finger guards on the probes. Work with others. 6. Before beginning all unknown measurements, set meter to highest possible range. 7. Before breaking a circuit for testing, turn off the power to the circuit. When disconnecting from a circuit, disconnect the hot lead first, then the common lead. 8. Disconnect the meter from the circuit before turning off any indicator, including motors, transformers, and solenoids. 3 Data Hold Button · The data hold button is used to capture and hold a reading on the LCD display. · Press the button again to release the reading.
