    The Diagnostics screen shows a "pH2" reading; this is the partial pressure of hydrogen measured by the hydrogen cell inside the Hycal probe in units of atmospheres. This is valuable when checking hydrogen cell accuracy when purging with a calibration gas of known hydrogen partial pressure.

    2. Position the arm appropriately over the melt. 3. Insert a Hycal probe into the arm's probe clamp. Slide the probe vertically so that it is 10- 20cm above the melt and tighten the arm's probe clamp to secure the probe.

    5 Guided Measurement mode Guided Measurement is a special mode that guides the operator through the measurement setup procedure prompting for all necessary information. The Hycal then automatically performs all necessary measurement preparation steps (purge cycles, delays etc.), conducts a pre-defined number of measurement analyses, and records the data.

    Default = 1 minute. Sets the measurement analysis time. 5.2.3 Measurement cycles Default = 1 cycle. Sets the number of measurement cycles. If set to >1 the Hycal will automatically repeat the measurement for the number of cycles set here (see Figure 32).

  • Page 57: Extra Purge

    However, in some cases different probes will be assigned individual measuring stations and it is not convenient to re-enter the probe calibration constants when moving the Hycal analyser to a different station. Setting the probe calibration mode to "Stations" allows the engineer to enter the probe calibration constants for each station in advance, so that operator simply needs to select the correct station before making a measurement.
  • Page 58 Page 51 Hycal User Manual V2.7 Figure 35: Guided Measurement Probe calibration setting Up to 4 stations may be configured, by pressing the "Configure stations" button. Each station is set to active or inactive and is given an ID, and a set of probe data as shown in Figure 36.
