measurement you would like to perform. Follow these steps to make a measurement: Connect the negative (-) side with the black test lead to the COM input. Connect the positive (+) side with the red test lead to the VΩHz input. - Page 11 Connect the black test lead to the COM terminal and the red test lead to the mA terminal for a maximum of 200 mA. For a maximum of 10 A, move the red test lead to the 10 A terminal. Turn circuit power off.

Page 12: Resistance Measurements
WARNING Do not connect more than 10 A DC current across the 10 A input terminal or the protection fuse will be tripped. Resistance Measurements The meter’s resistance ranges, Ω, are 200 Ω, 2 kΩ, 20 kΩ, 200 kΩ, 2 MΩ, 20 MΩ, 200 MΩ. Turn the rotary switch to the proper range. Follow these steps to make a measurement: Connect the black test lead to the COM input. -

mAhFE VΩHz TEMP Diode Figure 7. Connection for Diode Measurement WARNING Do not apply more than 1000 V DC across the terminals or they will be damaged. Continuity Test Continuity is a complete path for current flow. The meter’s continuity test is available to check for open/shorts of the circuit. -
Page 15: Capacitance Measurements
WARNING Do not apply more than 1000 V DC across the terminals or they will be damaged. Capacitance Measurements Capacitance is the ability of a component to store an electrical charge. The unit of capacitance is the farad (F). Most capacitors are in the nanofarad to microfarad range. -
