Options - with DIN plug or SMART plug
With the SMART connector on the probes, storing the data is needed only once - in the connector! The calibration data stays
with the probe - permanently. It can even be used on another instrument without any further action.
The SMART connector saves time and reduces error. If there are existing calibrated or uncalibrated probes, no problem,
CTR3000 automatically registers if a probe is SMART or normal.
4.3.2 Thermocouples
Thermocouples may be directly connected to the CTR3000 at the standard miniature sockets. These sockets are within a
temperature-compensated isothermal block which eliminates the need for an external ice point reference junction. However,
the CTR3000 may also be used with an external ice point reference for high-precision measurement and calibration work.
