3 Installing/Replacing the Batteries

Shift the lid at the back side of the probe and install/replace the four dry cells. The dry cells are not

installed on receipt of the instrument.

4 Operation

1. Install four AA cells. When using an external power supply, do not install the dry cells. Supply

power only through the external power supply.

2. Simply plug-in the BNC output connector to the vertical input of a oscilloscope, and connect the

auxiliary grounding terminal to a proper ground. If necessary, use a ground extention lead.

3. Select the proper range setting. For higher resolution and less noise when measuring signals

below 70 V, switch the attenuation to 1/10. Otherwise, set the attenuation to 1/100 when

measuring signals above 70 V.

4. If the offset voltage is large, short the top of input leads, and turn the ADJUST variable resistor (DC

voltage adjustment) using a flat-head screwdriver to adjust the offset voltage.

5. Connect the input to the circuits under measurement.
