3. indoor atmospheres with only non conductive pollution 10 When using devices with different measurement categories the lower measurement category applies For this probe because the measurement category of the alligator clip is lower when the probe and the alligator clip are used together measurement category CAT applies To use the probe under measurement category III conditions use it with the 701954 alligator clip 1000 Vrms CAT III sold separately IM 701926 01E 2 2
4. Series the 700938 or the 701934 3 Connect the BNC output connector to the oscilloscope input terminal and properly ground the auxiliary ground terminal If necessary use the auxiliary ground extension lead 4 Turn the power switch ON and warm up the probe for at least 30 minutes 5 Select the appropriate attenuation using the attenuation ratio selector For higher resolution and less noise when measuring signals less than or equal to 700 V switch the attenuation to 1 100 e When measuring signals greater than 700 V set the attenuation to 1 1000 6 f the offset voltage is large short the alligator clips and turn the ADJUST variable resistor DC voltage adjustment using an appropriate flat head screwdriver to adjust the offset voltage 7 Connect the two probe input leads to the two points of measurement differential measurement The performance declines if you only connect a probe input lead to a single point Make sure to connect both leads A To prevent electric shock and other accidents make sure to connect the probe output to the properly grounded oscilloscope so that the ground end shielded end of the BNC connector of the output cable is grounded Turn OFF the power to the circuit under measurement when connecting or disconnecting the probe from the circuit under measurement Connecting or removing the probe while the power is ON is dangerous Do not touch the probe after turning ON the power to the circuit under meas
