Connect the probe to the oscilloscope with the insulated BNC/BNC lead. ? Adjust the vertical zero adjustment of the oscilloscope if necessary. ? Select the attenuation ratio* and the vertical deviation of the oscilloscope in accordance with the conversion table below. ? NB: The POWER light must come on. The conversion table gives the real vertical deviation. Attenuation X

20 m [NOTE] The real vertical deviation in V/div is equal to the attenuation factor multiplied by the range of vertical deviation selected on the oscilloscope. It will be doubled in the case of use of a

50 ? load. Example: With the probe on factor x100, the oscilloscope on 0.5 V/div, the real vertical deviation is

100 x 0.5 =

50 V/div. With a 50? load on the input of the oscilloscope the deviation becomes

100 V/div. ?

10 EXT. POWER SOURCE: ? Power consumption of the probe is about 200mA, thus it not suit for battery, please use the accessory adapter only. ? If there are any damage on the adaptor, please contact us and use the adaptor supply by us only. If the input power over 12V DC will caused to the probe hard damage. MAINTENANCE: For maintenance, only use specified spare parts. The manufacturer can not be held responsible for any accident arising following a repair made other than its after sales service or approved repairers. CLEANING: This probe does not require any particular cleaning. If necessary, clean the case with a cloth slightly moistened with soapy water. WARRANTY: Unless notified to the contrary, our instruments are guaranteed against any manufacturing defect or material defect. They do not bear the specification known as the safety specification. Our guarantee, which may not under any circumstances exceed the amount of the invoiced price, goes no further than the repair of our faulty equipment, carriage paid to our workshops. REPAIR: Maintenance, repairs under or out of guarantee. Please return to product to your distributor. ?
