Page 12: Getting Started
Getting Started Using the Digital Multimeter With no signal present, set the rotary switch to the desired measurement function. Ensure proper insertion of the test leads so they correspond with the type of measurement you wish to perform, see the following instructions to understand the proper lead configuration for each measurement type. -
Page 13: Dc And Ac Current Measurements
DC and AC Current Measurements Turn the rotary switch to the corresponding symbol for the measurement you would like to perform. Current measurements can be made in low current or high current mode. In low current measurement mode, you can measure up to 400 mA. - Page 14 WARNING: Do not connect more than 400 mA DC current across the mA input terminal or the protection fuse will be tripped. Higher Current Measurements (Up to 20 A) Follow these steps to make measurements up to 20 A. 1. Connect the negative (-) side with the black test lead to the COM input.
