Module Considerations
This section lists important items and actions that can affect the operation of your
modules.
General Considerations
Environmental Operating Conditions
These modules are designed to operate in a temperature range of 0 °C to +55 °C
with non-condensing humidity. The maximum humidity is 80% R.H. at 31°C and
decreases linearly to 50% R.H. at 40°C. Do not use in locations where conductive
dust or electrolytic salt dust may be present.
These modules should be operated in an indoor environment where temperature
and humidity are controlled. Condensation can pose a potential shock hazard.
Condensation can occur when the modules are moved from a cold to a warm
environment, or if the temperature and/or humidity of the environment changes
quickly.
The table on
shows maximum voltage, current and power dissipation
ratings for each module. If conditions change, ensure that condensation has
evaporated and the instrument has thermally stabilized until pollution degree 1
conditions are restored before turning on power to the equipment.
NOTE
To reduce wear on the internal DMM relays, wire
like
functions on adjacent
channels.
NOTE
Pollution Degree 1
: No pollution or only dry, non-conductive pollution occurs.
The pollution has no influence (on insulation) (IEC 61010-1 2nd Edition).
NOTE
Pollution Degree 2
: Normally only non-conductive pollution occurs.
Occasionally, a temporary conductivity (leakage current between isolated
conductors) caused by condensation can be expected (IEC 61010-1 2nd
Edition).
