Introduction H25-IR

10 Instruction 3015-4342

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 to highlight or 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.
