Warning:

The maximum input is 600V. Do not attempt to take voltage measurements

that exceed this limit; electrical shock and damage to the clamp meter can result.

1. Set the rotary switch to the 'V' position (refer to figure 14).

2. Insert the test leads into the input terminals (black lead to COM and red to '+').

3. Connect the probe ends of the test leads in PARALLEL to the circuit to be measured.

4. The meter will automatically select the appropriate range and units (AC or DC).

5. Read the voltage and frequency values displayed on the LCD.

Note: The sensitivity for frequency measurements is 10V. The frequency range is 45 –

500Hz. If the frequency is less than 45 Hz, the LCD will display "------".
