User's Guide 1500Amp True RMS AC/DC Clamp Meter Model MA1500
Introduction Congratulations on your purchase of this MA1500 True RMS Clamp Meter. This meter measures AC Current, DC Current, AC/DC Voltage, Resistance, Capacitance, Frequency, Diode Test, Duty Cycle and Continuity. The molded case is designed for heavy duty use. This meter is shipped fully tested and calibrated and, with proper use, will provide years of reliable service.
SAFETY NOTES • • • • Do not exceed the maximum allowable input range of any function. Do not apply voltage to meter when resistance function is selected. Set the function switch OFF when the meter is not in use. Remove the battery if meter is to be stored for longer than 60 days. WARNINGS • • • • Set function switch to the appropriate position before measuring. When measuring volts do not switch to current/resistance modes. Do not measure current on a circuit whose voltage exceeds 600V.

Operation NOTES: Read and understand all Warning and Caution statements in this operation manual prior to using this meter. Set the function select switch to the OFF position when the meter is not in use. Non-Contact Voltage Detector WARNING: Risk of Electrocution. Before use, always test the Voltage Detector on a known live circuit to verify proper operation. 1. Rotate the Function switch to any measurement position. 2. Place the detector probe tip on the conductor to be tested. 3.
AC/DC Voltage Measurements CAUTION: Do not measure voltages if a motor on the circuit is being switched ON or OFF. Large voltage surges may occur that can damage the meter. 1. Rotate the function switch to the V position. 2. Press the MODE button to select AC or DC Voltage. 3. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive V jack. Touch the black test probe tip to the negative side of the circuit.
Capacitance Measurements WARNING: To avoid electric shock, discharge the capacitor before measuring. 1. Set the function switch to the CAP position. 2. Insert the black test lead banana plug into the negative COM jack. Insert the red test lead banana plug into the positive jack. 3. Press the MODE button to select capacitance (μF) measurements. 4. Touch the black test probe tip to one side of the device. Touch the red test probe tip to the other side of the device. 5.
Max/Min 1. Press the MAX/MIN button to activate the MAX/MIN recording mode. The display icon "MAX" will appear. The meter will begins recording and displaying the maximum value measured. 2. Press the MAX/MIN button and “MIN” will appear. The meter will display the minimum value measured during the recording session. 3. Press the MAX/MIN button and “MAX MIN” will appear. The meter will display the present reading, but will continue to update and store the max and min readings. 4.
Maintenance WARNING: To avoid electrical shock, disconnect the meter from any circuit, remove the test leads from the input terminals, and turn OFF the meter before opening the case. Do not operate the meter with an open case. Cleaning and Storage Periodically wipe the case with a damp cloth and mild detergent; do not use abrasives or solvents. If the meter is not to be used for 60 days or more, remove the battery. Battery Replacement 1. Remove the Phillips head screw secures the rear battery door. 2.
