AstroAI AM33D - Measuring AC and DC Voltage; Measuring DC Voltage

• Pay special attention to safety when measuring high voltages to
avoid electric shock or personal injury.
• Before using the Meter to test a known voltage or current,
confirm that the Meter functions work properly.
1 MEASURING AC/DC VOLTAGE:
MEASURING DC VOLTAGE:
• Insert the red test lead into the " VQmAJ1r
black test lead into the "COM" terminal
• Turn the rotary dial to the continuity test,
touch the red test lead and the black test I
ead to check whether they are normal
The buzzer will beep if the test leads are
normal.
• Turn the rotary dial to the "V.-=" area
with a white font. The screen will
display "000" indicating that the
measurement function is DC
voltage.
NOTE:
" terminal and the

(j) The test unit of "V*" area is " V "; If the number on the
white area is followed by "m", then the test unit is "mV'
@ If the measurement range is the
maximum, that is, 500 V setting,
"HV" will be displayed on the
screen
