Caution: Refer to Test Probe Caution.

A test lamp can simply and quickly test a low impedance circuit for voltage. A Digital Multimeter (DMM) should be used instead of a test lamp in order to test for voltage in high impedance circuits. While a test lamp shows whether voltage is present if the impedance is low enough, a DMM indicates how much voltage is present. In other words, if there is not enough current, the test lamp will not illuminate even though voltage is present.

The EL-35616-210 kit is Micro-Pack compatible and includes a 12 V test lamp.

To properly operate this tool use the following procedures.
