11. Frequency/Duty Cycle Measurement /Pulse
Width
1) Insert the red test lead into the V terminal and the black
test lead into the COM terminal.
2) Set the rotary switch to the measurement Hz% ms-Pulse,
press the key SELECT to select Hz or Duty% or ms-Pulse.
Connect the test leads to the signal source under test in
parallel as shown in Figure 11.
3) Directly read the measured values of frequency or duty
cycle or pulse width on the display.

.&.Attention:
• Simulation bar displays the frequency of the measured
signal for duty cycle and pulse width.
• Do not input a voltage with higher frequency than 30Vrms
to avoid personal injury.
• After completing all the measuring operations, disconnect
the connection between the test leads and the circuit
under test.
12. Temperature
1) Set the rotary switch to the measurement" mv·c•F",then
press the key SELECT to select Celsius °C or Fahrenheit
°F. Insert the temperature connector into four terminals
and connect two temperature probes to the temperature
connector. The probes detect the surface of the object
under test as shown in Figure 12.
2) Directly read Celsius or Fahrenheit temperature values
of the two surfaces under test on the display.
3) Press the function key MENU (Menu) to open one menu
item F2 in which basic temperature measurement can be
modified to enter the relative measuring mode. Press F4
to close the window of additional function. Press the
cursor keys 0il;0 to select menu items. The red cursor
key indicates the selected item, then press F1 to enter
corresponding value measurement. Press F2 to enter
relative value measurement, and press F4 to close the
window of additional function.
