Transmille’s EA001/EA001A has been designed to minimise typical errors associated with calibration of thermocouple meters that are ignored by other designs.

By making the thermocouple option external, the low voltage output (in the order of 0mV to 100mV, with accuracies in the microvolt level required for accurate simulation) is away from any heat generating components in the calibrator therefore reducing any localised thermal EMF effects.

The inclusion of a Thermocouple plug removes the need to find compensation cables of the correct type, which is a considerable source of error. If the wrong type of compensation cable (for example, when simulating a K type thermocouple, a J type compensating cable) is used there will be a significant error introduced through use of the wrong cable.

Finally, a temperature measurement is conducted at the connection with the UUT, in the thermocouple plug itself. This is measuring the cold junction as close to the internal measurement of the UUT as possible, removing localised differences in temperature.

Transmille products have been designed to most accurately represent the requirements of modern commercial laboratories and the typical equipment that is found inside.

Almost all modern computers are fitted with a USB interface, so to enable direct connection without the requirement for additional adapters a USB connection is provided.

IEEE 488/GPIB interfaces are typically quite expensive, and are another lead/connection to remember when performing on-site calibration work.

GPIB interface options are available on our multiproduct calibrators, and are included as standard on the 8000 series multimeters.

We believe that safety is a prime consideration of a laboratory, second only to performance of our products.

Imagine a situation where a laboratory technician has finished calibration for the day, and has disconnected the instrument under test, but left the voltage source on at a setting of 1000V AC.

Later that evening, a cleaner comes into your laboratory or facility and touches the test leads left on the bench, potentially receiving a very nasty shock. Transmille have added this safety feature to avoid situations of this type from happening.

There are, however, cases where the timeout wishes to be extended, or even disabled. This can be performed through the Calibrator Setup program via your computer, or can be disabled prior to shipping on request.
