5.8.3. Press the mode button to indicate and V on the display.
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.
5.9.
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.
5.11.

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
minutes of inactivity.

auto Power off
the auto off feature will turn the meter off after 15 minutes. to disable the auto power off feature, hold down the mode button and turn
the meter on.

use and store the meter in normal temperatures. temperature extremes can shorten the life of the electronic parts and distort or melt
plastic parts.
6.1.3.
Handle the meter gently and carefully. dropping it can damage the electronic parts or the case.
6.1.4.
Keep the meter clean. Wipe the case occasionally with a damp cloth. do not use chemicals, cleaning solvents, or detergents.
6.1.5.
use only fresh batteries of the recommended size and type. remove old or weak batteries so they do not leak and damage the unit.
6.1.6.
if the meter is to be stored for a long period of time, the batteries should be removed to prevent damage to the unit.
6.2.
Battery installation / removal
Warning!
to avoid electric shock, disconnect the test leads from any source of voltage before removing the battery cover
6.2.1.
turn power off and disconnect the test leads from the meter.
6.2.2.
open the rear battery cover by removing the screw using a Phillips head screwdriver.
6.2.3.
insert the battery into battery holder, observing the correct polarity.
6.2.4.
Put the battery cover back in place. secure with the screw.
Warning!
to avoid electric shock do not operate the meter until the battery cover is in place and fastened securely.
note:
if the meter does not work, check the fuses and batteries to make sure that they are still good and that they are properly
inserted.
6.3.
replacing the fuses
6.3.1.
disconnect the test leads from the meter.
6.3.2.
remove the battery cover.
6.3.3.
Gently remove the old fuse and install the new fuse into the holder.
6.3.4.
Always use a fuse of the proper size and value (0.5A/600V fast blow for the 600mA range, 10A/600V fast blow for the 20A range.
6.3.5.
replace and secure the rear cover, battery and battery cover.
Warning!
to avoid electric shock do not operate the meter until the fuse cover is in place and fastened securely.
