Warning
When the device input is getting through 42+ Vp-p (30Vrms), or on circuit of 4800+VA, to avoid
any potential short circuit or electric shock -
i. DO use only probes and adapter from original device accessories, or manufacturer's
recommended ones.
ii. Before working the device, DO check probes and accessories carefully to see whether any
mechanical damages exist, making sure probes and accessories in normal status.
iii. When device in non-working condition, to remove probes and accessories firstly, then put
them in certain places.
iv. When working the device in CAT II environment,
DO NOT get the 40+ V input voltage from earth surface through any non-isolated input;
DO NOT get the 40+ V input voltage of dropout voltage through any non-isolated input
v. DO NOT introduce input voltage larger than rated voltage, especially when probe
attenuation set in 1:1, since the voltage from probe tip will go through to the device itself.
vi. NO NOT contact the exposed part of metal BNC terminal directly by hand or any other body
part.
vii. DO NOT insert any metal object into connectors.
- Note -
i). The rated voltage mentioned in point v. is the fixed value of working voltage, matching
VACrms / 50 - 60Hz under AC sine wave application, and VDC under DC sine wave application;
ii). CAT II indicates local level for electrical appliance and portable device.
