Amprobe ACD-3300 Industrial-Clamp-Meters - Manual (Page 7)

Exercise extreme caution when: measuring voltage >20 V // current >10 mA // AC •
power line with inductive loads // AC power line during electrical storms // current,
when the fuse blows in a circuit with open circuit voltage >1000 V // servicing CRT
equipment.
Remove test leads before opening the case to change the battery.
•
Disconnect circuit power and discharge all high-voltage capacitors before testing •
resistance, continuity, diodes, or capacitance.
To avoid false readings, which could lead to possible electric shock or personal injury,
•
replace the batteries as soon as the low battery indicator () appears.
To avoid electric shock hazard, do not use the HOLD
•  mode to determine if a circuit
is live. Unstable readings will not be captured and displayed.
 CAUTIoN
For non-invasive ACA current measurements, clamp the jaws around only one single •
conductor of a circuit for load current measurement. More than 1 conductor will
cause false readings.
UNPACkINg AND CoNTENTS
Your shipping carton should include:
1 ACD-3300 IND or ACDC-3400 IND
1 Test lead set
1 9 V battery (installed)
1 Users Manual

INTRoDUCTIoN
The ACD-3300 IND and ACDC-3400 IND True RMS Clamp-On meters are autoranging
to 1000 ACA and 750 VAC / 1000 VDC. Their features include AC / DC voltage, AC /
DC current (ACDC-3400 IND), Frequency, Duty Cycle, Diode, Resistance, Capacitance,
Continuity tests plus Relative (ACDC-3400 IND). Model ACD-3300 IND also measures
temperature to 1000°C (1832°F)
AUXILIARy fEATURES
PEAk+/- Push button
It is used to record the peak + and - peak values for AC voltage and AC current
measurements.
Make the normal AC measurement and press the PEAK button. The PEAK value is
displayed on the secondary display and the actual value displayed on the primary
display. This function range locks on the normal range being used and may display OL if
the input exceeds the range maximum.
Note: If the PEAK ± button is pressed >2 sec, the PEAK function will enter to calibration
mode, the LCD will show “CAL” and the internal buffer will remember the internal
offset voltage when back in the measure mode. To exit the ‘CAL’ mode, turn the meter
OFF.
MAX/MIN button
The “MAX” displays the maximum value of a set of measurements. The “MIN” displays
the minimum value of a set of measurements. The “MAX/MIN” appears and flashes in
the LCD to display the value that is being measured. To exit, press MAX/MIN button for
more than 2 seconds
