SAFETY
As the NTC temperature sensor is a passive device, no voltages should be applied to the input terminals of the EMT 1900. The user must ensure that the
incorporation of the meter into the user’s equipment conforms to the relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for
Measuring, Control and Laboratory Use).
