Bacharach H25-IR Selecting Internal or External Calibration, Internal Calibration Selection

H25-IR Calibration

3 Calibration

When the instrument is supplied with an internal leak source, the operator can choose between two types of calibration: Internal or External. Internal calibration uses the instrument’s built-in leak source, while External calibration uses a customer supplied calibrated leak source.

If the instrument is supplied without a leak source, then the option of selecting the calibration type is removed from the menu system. The only option for this model of instrument is to calibrate using an external leak source.

3.1 Selecting Internal or External Calibration

Use the Main Menu > CAL DATA > CAL TYPE function to select either Internal or External calibration. If External calibration is selected, then also use the EXT RATE and EXT GAS TYPE functions to enter the characteristics of the external leak source.

Display the Calibration Data menu by first pressing both the ENT and ESC buttons on either the instrument’s front panel or Smart probe at the same time to display the Main menu. Next, use the Up and Down buttons to highlight “CAL DATA”, and then press ENT to display the Calibration Data menu.
