Allow at least 4 hours warm up of the 2100-A16 for the most accurate TC Readings.

Keep ambient airflow around the A16 to a minimum, mount it in a sealed box.

Keep TCs isolated from metal parts to prevent earth currents flowing, especially if other instruments measuring temperature are measuring at the same point.

TC inputs float at around ambient temperature +/-10 Deg C if no probe is fitted.

If a probe goes up and down in value, it is most likely to be a bad contact somewhere in the probe wiring or a faulty probe.

If the probes are connected via 2 pin plugs and sockets, keep the contacts clean and free from corrosion.

When calibrating probes, a TC probe responds faster to a rise in temperature, than going down to a lower temperature.

TC inputs on the A16 are not isolated from each other, or from the AO1 & AO2 outputs on the A16.

If the probe goes down in value when it should go up, the wires are reversed.
