1-3 Front Panel
Refer to Figure 1 and to the following numbered steps to
familiarize yourself with the meter’s front panel controls and
connectors.
1. Digital Display — The digital display has a 4000 counts
LCD readout with 82 segments analog bar graph, auto
polarity, decimal point, “ “ AC, DC, , , RANGE, H,
APO, REL, MAX, MIN, PMAX, PMIN and unit
annunciators. (PMAX, PMIN, REL are 105N / 106 only).
2. Rotary Switch — Select the Function and Range
desired.
3. COM Input Terminal — Ground input connector.
4. °C °F VΩ Hz Input Terminal — Positive input
connector for Volts, Ohms Capacitance, Frequency and
Temperature.
5. mA Input Terminal — Positive input connector for Amp
measurements (up to 400mA).
6. A Input Terminal — Positive input connector for Amp
measurements (up to 10A).
Push Switch Functions ( “MIN/MAX” and “Peak H” and
“Rel “ switch are for 105N / 106 only)
Push switch functions control the special measurement
modes of the meter. Some special modes can be nested
in other special modes, while some push functions reset
all existing special mode. The following table summarizes
the push functions in each special mode.

103N / 105N / 106 EN
Note :
1. BLUE KEY switch and RANGE Switch resets all special
modes other than HZ mode .
2. HZ switch is only used to toggle between frequency
measurement mode and voltage or current measurement
mode, and thus can not be nested in any other special
modes.
3. The bar graph always shows the current value, regardless
of special mode.
7. Light switch — Press the switch to turn on or turn o󰀨 the
back-light.
8. HZ — If “ HZ” switch is pushed in voltage or current
measurement mode, the meter enters frequency
counter mode with automatic range selection.
Therefore, pressing “RANGE” switch in HZ
mode does not change the frequency range.
However,“RANGE” switch changes the sensitivity
of frequency detection. If the input signal has a
small amplitude, the user shall increase the
sensitivity.
Note : Since HZ mode is treated as a temporary frequency
measurement in voltage or current mode, pressing
“RANGE” switch in HZ mode also changes the full
scale range of the original voltage or current mode
after VAHZ mode is cancelled.
9. PEAK H— The precision of PEAK hold mode
measurement can be enhanced by calibration. Calibration
for PEAK hold mode is invoked by pressing “PEAK H”
switch for more than 2 seconds until the “caL” is displayed.
Pressing the “Peak H” switch to toggle between PMAX
and PMIN.Pressing “Peak H” switch and held for longer
than one second to release the peak hold mode.
10. Range Switch, (Manual Range) — “Range” switch is
pressed to select manual ranging and to change ranges.
When “Range” switch is pressed on “RANGE” annunciator
on the LCD appears.
Press “RANGE” switch to select appropriate range to be
used.
Press “RANGE” switch and hold for 2 seconds to return
to Autoranging. In “ HZ” mode “RANGE” is not used
to change the full scale frequency range, but change the
sensitivity of frequency measurement.
11. Blue Switch — Press the switch to measure AC Voltage
/ Current or DC Voltage / Current in the voltage / Current
mode, or to measure Resistance or continuity or diode in
Ω / / mode or to measure Frequency or RPM in RPM
in Hz / PRM mode.

103N / 105N / 106 EN
12. MIN MAX — The meter displays the maximum or
minimum value of the input in MAX / MIN mode. When
“MIN MAX “ switch is pressed for the rst time, the meter
displays the maximum value. When “MIN MAX” switch
is pressed again, the meter displays the minimum value.
When “MIN MAX” switch is pressed for the third time,
the meter displays current input value and the “MAX”
“MIN” annunciator are blink. The meter returns to normal
operation if “MIN MAX” switch is pressed and held for
longer than one second. Pressing HOLD in MAX/MIN
mode makes the meter stop updating the maximum or
the minimum value.
13. REL — In REL mode, the LCD panel displays
D(current) - D(relative), where D(relative) is the last
value before “REL ” switch is pressed, and D(current)
is the current value. If “REL ” switch is pressed again
in REL mode, the meter displays the reference value and
the “REL” annunciator is blink. The meter returns to
normal operation if “REL ” switch is pressed and held
for longer than one second. Pressing “HOLD H” switch
in REL mode makes the meter stop updating the LCD
panel.REL with MIN MAX — MAX / MIN mode can be
nested in REL mode. The “MIN MAX’ meter displays the
maximum or the minimum value relative to the reference
when “MIN MAX” is pressed in REL mode.Before release
the REL function, the MAX/MIN function is needed to
release rst.
14. HOLD — HOLD mode makes the meter stop updating
the LCD panel. This mode can be nested in most of the
special modes. Enabling HOLD function in automatic
mode makes the meter switch to manual mode, but the
full scale range remains the same. HOLD function can
be released by changing the measurement mode,
pressing “RANGE” or “BLUE KEY” or push HOLD again.
When HOLD mode is nested in Peak Hor MIN / MAX
or REL mode to release the Peak Hor MIN / MAX or
REL function is needed to release HOLD function rst.
