Maximum input ranges
The table below and markings on the product indicate the threshold range and maximum input voltage for
the TA369 MSO pod. The threshold is the voltage at which the MSO pod distinguishes logic 1 from logic 0,
and the maximum input voltage is the maximum voltage that can be applied without risk of damage to the
instrument.
To prevent electric shock, do not attempt to connect voltages outside the maximum input voltage range.
Model
TA369
Signals exceeding the voltage limits in the table below are defined as "hazardous live" by EN 61010.
±70 V DC
Do not use the TA369 MSO pod to directly measure hazardous live voltages. Do not allow the MSO pod,
probes or cables to come into contact with exposed hazardous live conductors.
To prevent electric shock, take all necessary safety precautions when working on equipment where
hazardous live voltages may be present.
Do not exceed the voltage rating marked on any accessory. If an accessory is not marked with a voltage
rating on either the connector, cable or body, or if a protective finger guard is removed, then do not
exceed the EN61010 "hazardous live" limits above. When connecting one or multiple accessories and the
instrument together, the lowest voltage rating in the chain applies to the whole chain.
To prevent injury or death, do not connect the MSO pod directly to the mains (line power).
The TA369 MSO pod is designed for measurement of logic-level signals only. To prevent injury or death,
do not allow the probes, pod or interconnecting cables to come into contact with exposed conductors
exceeding the input voltage rating of ±40 V pk max, or to come into contact with hot or sharp surfaces that
may cause damage.
To prevent injury or death, do not use the product if it appears to be damaged in any way, and stop use
immediately if you are concerned by any abnormal behavior.
Grounding
The MSO pod's ground connection through the oscilloscope interface is for measurement purposes only.
The MSO pod does not have a protective safety ground.
Never connect the ground input (chassis) to any electrical power source. To prevent personal injury or
death, use a voltmeter to check that there is no significant AC or DC voltage between the MSO probe ground
and the point to which you intend to connect it.
Applying a voltage to the ground input is likely to cause permanent damage to the MSO pod, oscilloscope,
the attached computer, and other equipment.
To prevent measurement errors caused by poor grounding, always use the digital interface cable supplied
with the MSO pod.
