2.4.8 Serial Output

Leak rate data can be output as ASCII text in two formats.

After selecting the SERIAL OUTPUT function, the user can choose to have the text output to a file in two
formats.

Refer to section 4.6.

This function allows the string to be written to a file at the rate of 10 times per

second.

2.4.9 Probe Button

The PROBE BUTTON function selects what action is performed by the pushbutton on the Standard Probe with
LED and Pushbutton.

DISABLED

– No action performed.

MODE KEY

– Toggles the instrument between its Search and Measure modes.

ENTER KEY

– Performs the same function as the

ENT / ZERO

key on the instrument’s front panel.

Use the

Up

and

Down

buttons to highlight the desired setting. Press

ENT

to save the selection.

2.4.10 Reset Defaults

The RESET DEFAULTS function returns the instrument to its factory default settings per Appendix A.

This operation requires a three key press. Simultaneously press the ENTER+VOL buttons to reset
defaults.

2.5 Configuring the SETUPS Function

There are four user-defined Setups that allow the operator to quickly switch between frequently used
combinations of Gas Type, Range, Feedback Mode, Setpoint, and the Auto Zero Off condition. Program the
four Setup configurations as follows.

First enter the Setups menu by 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

“SETUPS”, and then press

ENT

to display the Setups menu.
