In most cases, this distance is also the required measuring distance. With focusable optics the focus distance can be changed continuously within a predetermined range, so the smallest possible spot size is always achieved.

  • Page 29 METIS M311 / M322 / H311 / H322 (12-pin) 6.2.8 Temperature Sub Range The temperature range can be scaled down in order to adapt it to specific measurement conditions (minimum range 51°C), e.g. to configure the automatic clear function of the maximum value storage (see 6.2.2). A modi- fied temperature range also can be set for the analog outputs to increase the resolution even further.
  • Page 30 METIS M311 / M322 / H311 / H322 (12-pin)  Limit the analog output: if the analog output is set smaller than the pyrometer’s temperature range, the resolution of the analog output is increased even further.  Enlarge the analog output: Entering a larger range as the pyrometer’s range will scale the output. The out- put at the beginning of temperature range is 0 or4 ma, at the end of the pyrometer’s temperature range the current output is that corresponding to the enlarged temperature range.
