Introduction H25-IR

1.8 Menu System

Press the ENT and ESC keys at the same time to access the Main menu.

The menu system enables the operator to perform such functions as setting up the instrument, viewing logged readings, configuring the four user-defined setups, entering calibration data, and viewing the instrument’s diagnostic readings.

The buttons on the instrument’s front panel and probe are mapped the same and can be used inter- changeably, with exception of the CAL button.

Select a menu item by first using the Up and Down buttons to highlight the desired item, and then pressing ENT to select that item and display its data screen. After an item has been selected, use the Left, Right, Up, and Down buttons as necessary to highlight and change data within a screen. Pressing the ENT button saves the new data, while pressing the ESC button aborts the operation and displays the previous screen.
