Push ~ Hz during an AC voltage or current measurement. 2.
Range Guide for Ohms (Ω): 300 = Meter indicates actual resistance 3k = Multiply meter display reading by 1,000 to acquire actual resistance. 30k = Multiply meter display reading by 1,000 to acquire actual resistance. 300k = Multiply meter display reading by 1,000 to acquire actual resistance. 3M = Multiply meter display reading by 1,000,000 to acquire actual resistance 300M = Multiply meter display reading by 1,000,000 to acquire actual resistance.
Diode Testing Capacitance Circuit Connection: Hz Hz True RMS True RMS Function Resolution Accuracy Max. Test Max. Open Current Circuit Voltage 1mV +(1.5% +5)* 1.5mA 3V * For 0.4V to 0.8V. Overload Protection: 600V rms max Diode Check: To ensure a proper functioning diode, the meter will develop a voltage across the component from a test current. The diode test function allows measurements of forward voltage drops across diode and transistor junctions. 1.
Continuity Check General Specifications Circuit Connection: LCD Display: Bar Graph Display: Polarity Indication: Overrange Indication: Low Battery Indication: Hz Size (WxHxD): True RMS Sampling: To Verify Continuity: A continuity test ensures that all circuit connections are intact. 1. Plug the black test lead into the COM port and the red test lead into the VΩHz port. 2. Set the rotary switch to the Ω position. 3. Press the blue button until is shown in the display. 4.
Maintenance Warning To avoid electrical shock, remove test lead before opening the cover. Repairs or servicing not covered in this manual should only be performed by qualified personnel. Battery Installation or Replacement: The #61-480 is powered by one 9V battery. 1. Remove the test leads from the front terminals and turn the meter off. 2. Remove the screw from the battery cover and lift to remove. 3. Lift battery box and replace batteries. 4.
