Warning
To avoid electrical shock remove the test leads before opening the
case or battery cover. Do not operate with battery cover open.
To avoid electrical shock when performing resistance tests, remove
all power from the circuit to be measured.
To avoid electrical shock, first connect the test leads to the meter
inputs before you make connection to the circuit under test.
To avoid electrical shock, do not touch the test lead tips, test points
or terminals when pressing TEST.
4-1 How to connect test leads.
Connect the red test lead into the “ VΩ ” jack and the black lead
into the “ COM ” jack.
4-2 Battery Check & Replacement c Manual data memory and read location indicator.
1). If battery power is not sufficient, The LCD will display “
BT
”.
Replacement of 6 ea. new batteries, type 1.5V size “AA” is required.
d Beeper symbol shows if beeper turned on in Ω function.
e High voltage warning symbol flashes, if voltage ≧ 30V is present on the
probes.
2). Use a screw drive to unscrew the screw secured on battery cover.
Take out the used batteries and replace 6 pcs new batteries.
3). Place back the battery cover and secure the screw. f Voltage applied to the probes in MΩ function, Resistance reading held
from the last measurement in MΩ and LoΩ functions and DC Voltage
reading in
~
V function.
4-3 Auto-Power-Off
1). The meter automatically turns off after 15 minutes of non-use. In
the LoΩ mode the meter turns off after 5 minutes of non-use.
g Zero symbol is on if test leads are zeroed out.
2). To turn the meter back on, turn the rotary switch to OFF, then to
the desired function. h Lock symbol is on if the TEST mode is locked in MΩ or LoΩ functions.
i Low battery symbol.
4-4 Test Leads Check
Set the range select switch to the “Ω ” range. Connect the
alligator clips to the test leads. Connect the alligator clips together.
The indicator should read <0.5 Ω . When the leads are not
connected the display will read infinity indicated by “－
－ ”. This
will ensure that test leads are under working condition.
j Main display reading for all functions.
k Analog bar graph displays resistance on a logarithmic scale and
voltage on a linear scale. The value always tracks the main display.
