PRIMARY DISPLAY:
The Primary Display is located in the middle
of the screen and uses the largest font. It shows the dominant
impedance parameter reading typically with 5 digits displayed.
SECONDARY DISPLAY:
The Secondary Display is located just above the
Primary Display. It shows the minor impedance parameter reading.
TEST PARAMETERS:
The Test Parameters area is at the top of the
screen and provides information about current test conditions
such as Test Frequency, Range, Test Signal level, Test Model.
DEVICE STATUS:
The Device Status area is at the bottom of the
screen and provides information about the current Test Mode
and settings of the device: Hold, Audio and Battery Status.
TEST MODE INDICATOR:
The Test Mode Indicator sign is
located immediately to the left of the Primary Display.
Symbols A, R, L, C, |Z|, ESR and Diode indicate Auto,
Resistance, Inductance, Capacitance, Impedance and ESR
measurement and Diode Test mode respectively.
DISPLAYED PARAMETERS
The measurement mode setting (R, L+R, C+R, C+D, L+Q,
|Z|, ESR and AUTO) determines the measurement
type and the displayed parameters
R MODE:
Resistance is shown on the Primary The resistance
displayed is either the equivalent series or parallel resistance
of the DUT. Resistance units are mΩ, Ω, kΩ, or MΩ.
L+R MODE:
Inductance is shown on the Primary Display and the series
resistance on the Secondary Display. The units of inductance are µH,
mH or H. Resistance is the real part of the impedance. Resistance
units are mΩ or Ω. Serial equivalent circuit is used in this mode.
L+Q MODE:
Inductance is shown on the Primary Display and
the quality factor Q on the Secondary Display. Inductance
units are µH, mH or H. Q is the ratio of the imaginary part of the
impedance to the real part of the impedance. Q is dimensionless
and the same for both series and parallel representations. A
good inductance has a large L and a small R and thus a high Q..
