5.8.3.
Press the MODE button to indicate
5.8.4.
Touch the test probes to the diode under test. Forward voltage will typically indicate 0.400 to 0.700V. Reverse voltage will indicate
"OL". Shorted devices will indicated near OV and an open device will indicate "OL" in both polarities.

AUTORANGING/MANUAL RANGE SELECTION
When the meter is first turned on, it automatically goes into Autoranging. This automatically selects the best range for the
measurements being made and is generally the best mode for most measurements. For measurement situations requiring that a range
be manually selected, perform the following:
5.9.1.
Press the RANGE key. The "AUTO" display indicator will turn off.
5.9.2.
Press the RANGE key to step through the available ranges until you select the range you want.
5.9.3.
To exit the Manual Ranging mode and return to Autoranging, press and hold the RANGE key for 2 seconds.
Note: Manual ranging does not apply for the Capacitance and Frequency functions.
5.10.
MAX/MIN
Note: When using the MAX/MIN function in Autoranging mode, the meter will "lock" into the range that is displayed on the LCD when
MAX/MIN is activated. If a MAX/Min reading exceeds that range, an "OL" will be displayed. Select the desired range BEFORE entering
MAX/MIN mode.
5.10.1.
Press the MAX/MIN key to activate the MAX/MIN recording mode. The display icon "MAX" will appear. The meter will display and hold
the maximum reading and will update only when a new "max" occurs.
5.10.2.
Press the MAX/MIN key again and the display icon "MIN" will appear. The meter will display and hold the minimum reading and will
update only when a new "min" occurs.
5.10.3.
To exit MAX/MIN mode press and hold the MAX/MIN key for 2 seconds.

MODE
Press MODE key the selection of double measured functions which are present at display is possible. In particular this key is active in
V· ·CAP·Ω position to select among resistance test, diode test, continuity test and capacitance test, and in current position to select
between AC or DC current measurements.
5.13.
HOLD / FLASH LIGHT
The hold function freezes the reading in the display. Press the HOLD key momentarily to activate or to exit the HOLD function.
Press the HOLD key for >1 second to turn on or off the FLASH light function .The flash light and will automatically power OFF after 5
