INSTRUCTION MANUAL RT-ZD002 / RT-ZD003 25 MHz Active Differential Probes RT-ZD002 (1337.9700.02) RT-ZD003 (1337.9800.
These probes are in compliance with IEC-61010-031 CAT III, Pollution Degree 2 1. Safety Terms and Symbols Terms appear in this manual: ___________________________________________________ WARNING. Warning statements identify conditions or practice that could result in injury or loss of life. ___________________________________________________ CAUTION. Caution statements identify conditions or practice that could result in damage to this product or other property.
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 measurement instrument is properly grounded.
. Installation a. Simply plug-in the BNC output connector to the vertical input of a general purposed oscilloscope or other measurement instrument. The measurement instrument must be ground referenced. b. Connect an appropriate power source to the probe or enter the batteries, then turn it on. c. Select the proper attenuation ratio. When measuring signals below 70 V or 140 V, switch the attenuation ratio to 1/10 (RT-ZD002) or 1/20 (RT-ZD003) in order to get higher resolution and less noise.
6. Available Power Sources • 4 x AA batteries • USB Power Cord, for oscilloscopes which offer USB connector. The supplied voltage must be less than 12 V and greater than 4.5 V, otherwise the probe could be damaged or can’t be operated properly. Polarity is “+” inside and “–” outside. For wrong polarity a built-in circuit protects the probe, no danger or damage will occur. When the voltage of the cells become too low, the power indicator on the front panel will flicker. 7.
