Must be Grounded This probe is grounded with the shell of BNC connector and an auxiliary grounding terminal, through the grounding conductor of the power cord of the measurement instrument. Before making connections to the input leads of this probe, ensure that the output BNC connector is attached to the BNC connector of the measurement instrument and the auxiliary grounding terminal is connected to a proper ground, while the measurement instrument is properly grounded.

4. Installation a. Simply plug-in the BNC output connector to the vertical input of a general purposed oscilloscope or other measurement instrument, and connects the auxiliary grounding terminal to a proper ground. The measurement instrument must have a ground referenced. b. Connect an appropriate power source (mains adaptor, battery pack or power lead) to this probe and then turn it on. WARNING. To protect against electric shock, use only the accessories supplied with this probe. c.

9. Inspection Procedure a. Connect the BNC output connector to the vertical input of a general purposed oscilloscope. b. c. d. e. Connect an appropriate power source to this probe and then turn it on. Set the oscilloscope to DC coupling and 1V/div. Center the trace on the display. Connect the inputs of the probe to power lines. Then, a 50Hz/60Hz sine-wave of proper amplitude will be displayed on the screen of the oscilloscope and this means the probe is working properly. 10.
