Read the resistance on the LCD display.
5.4 Frequency or % duty cycle measure-
ments
In order to realise frequency or % duty cycle measurement it is
necessary to realise the following actions:

Insert the black test lead banana plug into the negative COM
jack and the red test lead banana plug into the V· ·°C·°F·Hz
positive jack,

Set the function switch to the V Hz position,

Press the Hz/% button to select the Frequency (Hz) or Duty
cycle (%)function,

Touch the test probe tips across the circuit under test,

Read the Frequency value on the display,

Duty cycle measurement: When the duty cycle is less than
10.0%, the LCD panel shows UL. When the duty cycle is more
than 94.9%, the LCD panel shows OL,

The display will indicate the proper decimal point and value,

Press the HZ/% button again to return to the voltage mode.

Temperature measurements

In order to realise temperature measurement it is necessary to
realise the following actions:

Set the function switch to the Temp position,

Insert the Temperature Probe into the negative COM and the
V· ·°C·°F·Hz positive jacks, observing polarity,

Touch the Temperature Probe head to the device under test.
Continue to touch the part under test with the probe until the
reading stabilizes,

Read the temperature on the display. The digital reading will
indicate the proper decimal point and value,

Use the MODE button to select
