- indoor use
- altitude up to 2000m
- temperature 0°C to +50°C
- maximum relative humidity 80% for temperatures up to 31°C decreasing
linearly to 40% relative humidity at 50°C.
Use of the probe on uninsulated conductors is limited to 300V r.m.s or d.c.
and frequencies below 1kHz.
Safety in its use is the responsibility of the operator who must be a suitably
qualified or authorised person.
Do not use the probe if any part of the probe including the lead and connector(s)
