NOTE: To maximize thermal stability,
final calibration should be performed in
the operation installation, allowing
approximately 1 to 2 hours for warm up
and thermal equilibrium of the system.

Note1: All modules are designed and tested to operate in ambient
temperatures from 0 to 55°C, when mounted on a horizontal DIN rail.
When five or more modules are mounted on a vertical rail, circulating air
or model DRG-HS01 Heat Sink is recommended.
