Preparing The 515 Pump - Waters 515 HPLC Operator's Manual

Tip:
When you need to edit a digit in the Flow parameter setting, press
the Edit/Enter key until the cursor is positioned over the digit you want
to change. You cannot move the cursor directly to the left; if you need to
edit a digit to the left of the blinking cursor, simply continue to press
Edit/Enter until the cursor wraps to the appropriate digit.
3. Use the Up or Down key to increase or decrease the value of the digit,
respectively. If the parameter value is not numeric (psi, for example),
use the Up or Down key to display a different parameter selection (bar,
for example).
4. If necessary, repeat steps 2 and 3 until all parameter values are correct.
5. Press Menu to store the parameter and display the next menu item.
Tip:
In Rem mode, flow rate, high-pressure limit, and low-pressure limit
parameters set at the pump are superseded by corresponding settings at the
remote device.
