Module Considerations

This section lists important items and actions that can affect the

operation of your modules.

General Considerations

N O TE	To reduce wear on the internal DMM relays, wire like functions on
	adjacent channels.

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% at 40 °C or higher. 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 following table shows maximum voltage 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.
