If you are planning to install the
gauge facing downward (horizontally, or at an angle), please specify
at the time of order, as the unit must be adjusted prior to shipment.
·
When measuring flammable gases, or
using switch in a flammable atmosphere, use anti-explosive construction and
contact signal exchangers.

Reliability
of the general load contact is reduced when used with very low voltage or
current; the low load model should be used in such cases.
·
Always
use surge protection circuits to prevent contact damage when using inductive
load circuits such as relays.
