This is the user manual of a 25MHz ±700 V differential probe, which includes safety instructions and product features
This manual outlines safety requirements for the TA041 probe, including maximum input voltage limits (1000 V RMS CAT III), mandatory grounding via the BNC shell and auxiliary terminal, and precautions against wet conditions, explosive atmospheres, and uncovered operation. It also describes proper use of fused test leads and the need to verify grounding before connecting the probe to measurement instruments.
The document details the probe’s technical specifications such as 25 MHz bandwidth, 1:10/1:100 attenuation, and power options (four AA cells or 6 V/9 V DC adapters). Installation steps cover connecting the BNC output to an oscilloscope, attaching the grounding terminal, selecting attenuation, and using the appropriate input leads. Additional information includes dimensions, weight, operating temperature, and cleaning instructions.

The absolute maximum voltage is ±1400 V (DC + Peak AC) or 1000 V RMS CAT III.
The probe must be grounded via the BNC shell and the auxiliary grounding terminal, and you should verify the ground connection before attaching the input leads.
It can be powered by four AA cells, a 6 V DC/60 mA mains adaptor, or a regulated 9 V DC/40 mA mains adaptor.
The probe has a bandwidth of DC to 25 MHz (-3 dB).
