Operation Instructions

Conditions of Use

Environment: Indoor use or temporary outdoor use. For long term or permanent outdoor use, a suitable enclosure may be required.
IP67 Rating: LC gauges with external thermal probes must have the thermal probe cable installed in M12 connector on gauge to maintain IP67 rating.
LC gauge requires (2) AAA Batteries, power from a PC via USB or power from AC power adapter D-000410 via USB to operate.
RF Exposure Statement: The LC30 device when used with approved antenna complies with the FCC and IC portable RF Exposure limits set forth for an uncontrolled environment and is safe for intended operation as described in the user manual. To comply with RF exposure limits established in the ANSI C95.1 standard, the distance between the antenna and the user should not be less than 25 cm (10 inches) for USA and 34 cm for Canada. Further RF exposure reduction can be achieved if the product can be kept as far as possible from the user’s body.

Installation Instructions

Ensure that gauge is oriented in such a way that the “Power” button is always easily accessible.
If pressure sensor option is installed, then seal pressure connection with thread sealant prior to assembling it in any pressure system.
If temperature sensor option is installed, then connect thermal probe using a rated thermal well or other approved device.
Place gauge in area that is protected from damage from weather, excessive temperature, impact or humidity.
