Warning
When the device input is getting through the voltage larger than 42 Vp-p (30Vrms), or on circuit of
4800+VA, to avoid any potential short circuit or electric shock -
i. DO use probes and adapter come along with the original device, or those ones recommended by Lilliput.
ii. Before working the device, DO check probes and accessories carefully to see whether any mechanical
damages exists, making sure probes and accessories in normal-working status.
iii. When device in non-working condition, to remove probes and accessories firstly, then put them in
suitable 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 input the voltage larger than the rated one, 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 human body
part.
vii. DO NOT insert any metal object into device 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.
