INSTRUCTION MANUAL TT-SI 9010A 70MHz Active Differential Probe
These probe is in compliance with IEC-61010-031 CAT I, 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 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 auxiliary grounding terminal is connected to a proper ground, while 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, and connects the auxiliary grounding terminal to a proper ground. The measurement instrument must have a ground referenced. b. Connect an appropriate power source to this probe and or enter the batteries, then turn it on. c. Select the proper attenuation ratio.
6. Offset Adjustment If the offset voltage is too large, short the input leads and turn the adjust variable resistor (DC voltage adjustment) which you find in the hole of the panel by using a flat-head screwdriver until the offset voltage is lowest. 7. Available Power Sources a. 4 x AA batteries b. c. d. Mains adaptor (6VDC/60mA or regulated 9VDC/40mA), Lemo® Power Cord, for oscilloscopes with power output - Lemo® connector. Probus® Power Cord, for oscilloscopes with power output - Probus® connector.

11. Differential’, Common Mode’ and ‘Absolut max.’ Voltage Range limit is the lesser of the ‘DC+Peak AC’ and RMS values. Input voltage at positive input lead = V(+) / Input voltage at negative input lead = V(-) - Differential Range= V(+) –V(-) - Common Mode Range= [V(+) +V(-) ] /2 The input-specification of differential range and common mode range has to be meet at the same time so that output specification could be meet.
