Measuring the pulse duration in %
The DMM can display the pulse duration of an AC voltage signal’s positive half wave as a percentage of the entire
period.
Follow the steps below to measure the pulse duration in %:
• Turn the DMM on and select the “%” measurement mode. Pulse duration
measurements can be made with normal or low impedances (LoZ %). Only
select the “LoZ %” function in special circumstances. “V
” will appear on
the display.
• Press the “Hz%” button twice. “%” will appear on the display.
• Plug the red lead into the Hz terminal (K) and the black lead into the COM
terminal (I).
• Connect the two measuring probes to the object that you want to measure (e.g. signal generator or circuit).
• The pulse duration of the positive half wave is shown as a percentage value on the display. For a symmetrical
signal, the pulse duration will be displayed as 50%.
• After measuring, remove the test leads from the measured object and turn the multimeter off.
f) Measuring the temperature
When taking a temperature measurement, only allow the temperature probe to come into contact
with the surface of the measured object. The multimeter must not be exposed to temperatures
below or in excess of the operating temperature, as this may lead to incorrect measurements.
The temperature probe must only be used on voltage-free surfaces.
The multimeter features a wire sensor that can measure temperatures from -20 to + 230 °C. To use the full tempera-
ture range (-20 bis +1000 °C), purchase a Type-K thermal sensor. The meas-
urement adapter that comes with the multimeter is required to connect Type-K
sensors with a miniature connector.
All K-type thermal sensors can be used for taking temperature measurements.
The temperature can be displayed in °C or °F.
Follow the steps below to measure the temperature:
• Turn on the DMM and select the “TEMP” measurement mode. “°C” will appear
on the display.
• Use the “MODE” to change the temperature unit.
• Insert the temperature probe into the temperature measuring adapter in the
correct polarity. The thermocouple plug can only be inserted into the measure-
ment adapter in the correct polarity. Do not use force when inserting the plug.
• Insert the positive terminal on the measurement adapter into the temperature
measurement socket (K) and the negative terminal into the COM measure-
ment socket (I).
• The temperature will appear on the display.
• “OL” indicates that the measurement range was exceeded or the sensor was
disconnected.
