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 m
Ω
,
Ω
, k
Ω
, or M
Ω
.
L+R MODE:
Inductance is shown on the Primary Display and the series
resistance on the Secondary Display. The units of inductance are
μ
H,
mH or H. Resistance is the real part of the impedance. Resistance
units are m
Ω
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
μ
H, 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..
