The Keypad
Accessing Functions
Use the instrument keypad on the lower left front section of the instrument to
view and change all settings. Pressing a key once brings up the first item in a
menu of parameters connected with that key. Use the cursor keys (
▲ , ▼ ) to
scroll through the menu items available for control. As you scroll to each item,
the instrument display shows the current value of the setpoint for that
parameter.
Editing Setpoints
To edit a setpoint:
1. Press the key sequence for the parameter.
2. Key in the new value using the numeric keypad.
A flashing
* appears to the left of the new value as you enter it.
3. Press Enter to make the new value part of the active method.
If the new value is not within the allowed range, the sampler displays a
message showing the allowed range. Press any non–number key to remove
the error message.
At any point in a menu, press Clear to return to the top–level display.
See Table 2 (G1883) or Table 3 (G1289/G1290) for a quick reference of the keys
and their functions.

The table below lists all the keys available on your instrument, and summarizes
