7.2.2 Secondary Parameter
In Auto mode for inductors quality Q factor is displayed for Q>1 and series Resistance Rs for Q <1, and
for capacitors, loss tangent for C < 1
μF and ESR for C> 1 μF. Aut omatic secondary parameter selection
does not work if the Test Signal is set to Automatic, R is used as the secondary parameter in this case.
7.2.3 Test Frequency
This menu item allows to select the frequency of the test signal. In Auto mode, the device automatically
selects a frequency of 100Hz, 120 Hz, 1 kHz or 10 kHz, depending on the rating and type of the
component. Users can also manually select the test frequency. A higher frequency is used for measuring
small values of capacitances and inductances. Resistor measuring are always made at 1 kHz unless
RDC+LED Mode is selected. If 100 kHz frequency is required, press the jog-wheel and hold for 2 beeps.
7.2.4 Test Signal Level
For more stable readings, select 0.65Vrms or Auto signal level. Auto is best for measuring loose
components and in-circuit measurements of R, C, L. When measuring on boards, if at high test signal
level opens p-n junctions of semiconductors components causing an error in the measurements, then
the signal level is automatically reduced to 0.1 V peak-to-peak and the value is re-measured. In this case,
the screen shows the diode symbol and the direction of the p-n junction.
7.2.5 Period
Increased measurement time results in more stable readings, reduced time results in faster updates on
the screen.
7.2.6 SER/PAR Mode
This is used to select the equivalent circuit depending on the characteristics of the element.
7.2.7 Sound
The device will beep when the resistance is less than 10 Ohm or a short circuit is found.
7.2.8 C-Voltage
This setting has to be selected in the menu when evaluating electrolytic capacitors for rejection by ESR.
The voltage is written on the capacitor’s housing.
7.2.9 Sample Hold
When selected, the device will hold measurement data on the screen. A beep will sound when the
measurement is made and the values are held on the screen after the component has been
disconnected from the device. The device will only reset when a new component is measured or the test
probes are shorted.
