6-6 Continuity Check (400Ω range fixed)
※ The continuity check mode is enabled by pressing the mode selector switch on resistance range. " " is indicated on the display to show the instrument in the continuity check mode. The buzzer beeps, if the resistance under test is 20.0Ω or less.
DANGER
●Never use the instrument on an energized circuit.
● Do not make measurement with the battery compartment cover removed.
● Keep your fingers and hands behind the protective fingerguard during measurement.
①Set the function selector switch to the " Ω" position.
② Slide the terminal cover to the left to disclose the V/Ω and COM terminals. Plug the red test lead into the V/Ω terminal and the black test lead into the COM terminal.
③ With the tip of the test leads shorted together, press the Zero
Adjust/Reset button to offset the resistance of the test leads.
④ Press the mode selector button once to enter from the normal mode to the continuity check mode. " " should be indicated on the display.
⑤ Connect the tip of the test leads to the circuit under test. If the resistance is 20.0Ω or less, the buzzer beeps.
6-7 Frequency Measurement
● On ACA or ACV range, the frequency of the current or voltage under test can be counted and shown on the display.
● In the frequency measurement mode, "Hz" is indicated on the display.
● Trigger threshold is approx. 10V for AC voltage and approx. 40A for AC current.
