8.4 Measuring Frequency
Step 1:
Make sure the lead cables for measurement are not connected to the measuring instrument under
test.
Step 2:
Using the
〔
FREQ
〕
key, select frequency measurement function.
Step 3:
Connect the lead cables for measurement to the measuring terminals of the measuring
instrument under test.
Step 4:
Using the measurement
〔
RANGE
〕
key, select the suitable range from 500Hz,5KHz,50KHz.The
selected function and the measured value and unit shall be shown on the LCD.
8.5 Measuring Continuity
Continuity measurement is used to detect the intactness of the circuit (e.g. a resistance lower than 200). Using
the
〔 〕
key, select continuity measurement function. LCD displays continuity symbol “ ”on the LCD.
Connecting the devices as shown in Figure8, the beeper sounds continuously if the loop circuit resistance
under measurement is less than 200
Ω , and the LCD shows the “OPEN” or “CLOSE” symbol.
