AstroAI AM33D - Measuring Resistance

CURRENT NOTES:
• Choose the maximum setting to measure the unknown current
first, and then select the appropriate range according to the
current.
• If you insert the red test lead into the IOAjack, be sure to insert
the test lead back into the "VQmA$1r"jack after the test to avoid
forgetting to switch the jack for the next operation and thus
burning the Multimeter.
• When testing a high current, for safety reasons, each
measurement time should be less than 10 seconds, and the
interval time between tests should be greater than 15 minutes.
• When testing the current, there must be a load in the circuit. Do
not connect the multimeter in series with the circuit without a
load to measure; doing so can potentially damage the Meter.
• Do not apply a current exceeding the Meter's range to avoid
damaging the Meter.
IV.MEASURING RESISTANCE:
• Insert the red test lead into the "VQmA-rL-" terminal and the
black test lead into the "COM" terminal
• Turn the rotary dial to the continuity test,
touch the red and the black test leads to
check whether they are normal. The buzzer
will beep if the test leads are normal.
• Turn the rotary dial to the"Q" area with a
yellow font. The screen will display "1"
indicating that the measurement function is
resistance.
