6.4 Measuring Frequency
Step 1:
Ensure that the test lead cables are not connected to the instrument under test.
Step 2:
Using the function selector key
(FREQ)
, select the frequency measurement function.
Step 3:
Connect the test lead cables to the measuring terminals of the instrument under test.
Step 4:
Using the measurement
(RANGE)
key, select the suitable range (500Hz, 5KHz, 50KHz).The selected function, the
measured value, and the unit is shown in the upper part of the LCD.
6.5 Measuring Continuity
Continuity measurements are used to detect the completeness of a circuit or wire (e.g. a resistance smaller than 250 ohms).
Using the function selector key
(
)
, select the continuity measurement function. The LCD displays the continuity symbol
“
”on the upper area. Connect the device as shown in Figure 8; the beeper will sound continuously if the loop circuit
resistance is below 250
Ω
; The LCD shows the circuit OPEN or CLOSED icon.
6.6 Measurement-filtering function
The measurement-filtering function stabilizes the measured value displayed on LCD. In the DCV or DCmA function, pressing
the
〔
AVG
〕
key facilitates an averaging calculation of the samples and the LCD shows the “AVG” symbol. Pressing the
〔
AVG
〕
key again cancels the calculation and the “AVG” symbol switches OFF.
6.7 Measured Value holding function
The read-hold function can be used to freeze a measurement (the held measurement is shown on the upper area of the
LCD). Pressing the
〔
HOLD
〕
key selects the read-hold mode and the LCD displays the “HOLD” symbol. To cancel the
selection, press the
〔
HOLD
〕
key again and the “HOLD” symbol will switch OFF.
