7. Operating Instructions
7-1 Attention before operation
Check 7V battery. If the battery voltage is less than 7V, display will show “ “,the battery should be replaced at this time to
ensure meesuring precision. Pay attention to the “
“ besides the input jack which shows that the input voltage or current
should be within the specified value. The range switch should be positioned to desired range tor measurement before operation.
7-2 Measuring DC Voltage
Connect the black test lead to COM jack and the red to
V
Ω
mA jack.
Set
the rotary switch at the desired
range position.
Connect test leads across the source or bad under measurement. You can get reading from LCD. The polarity of the red lead
connection will be indicated along with the voltage value.
NOTE:
1. When the value scale tobe measured is unknown beforehand, set the range selector at the highest position.
2. When only the figure '1' or '-1' is displayed, it indicates over-range situation and the higher range has tobe selected.
3. “
“ means you can't input the voltage more than 600V, it's possible to show higher voltage, but it may destroy the inner
circuit or pose a shock.
4. Be cautious against shock when measuring high Voltage.
7-3 Measuring AC Voltage
Connect the black test lead to COM jack and the red to V
Ω
mA jack. Set the rotary switch at the desired V~ range position.
Connect test leads across the source or load under measurement. You can get reading from LCD.
NOTE:
1. When the value scale tobe measured 15 unknown beforehand, Set the range selector at the highest position.
2. When only the figure '1' or '-1' 15 displayed, it indicates over-ange situation and the higher range has to be selected.
3. “
“ means you can't input the voltage more than 600V, it's possible to show higher voltage, but it may destroy the inner
circuit or pose a shock.
4. Be cautious against shock when measuring high Voltage.
7-4 Measuring DC Current
Connect the black test lead to COM jack and the red to the V
Ω
mA jack for a maximum 200mA current, for a maximum 10A
