Function
Turns the method clock off (Hold) and on (Run).
When the method clock is in Hold, pressing Hold/Run starts the clock
at either the initial step of a new method or, if resuming an interrupted
method, at the time at which the clock was put in Hold.
When the method clock is in Run, pressing Hold/Run stops the
method clock, thereby "holding" the method and freezing the current
conditions.
If the Dionex ED50A is in Voltammetry mode, pressing Hold/Run
runs or holds the waveform program.
Changes the method clock time to
specified by the method to occur. This button functions only when the
detector is under Method control (see Section 2.5.3).
If the method is running, it continues running. If the method is in Hold,
the method clock executes the initial conditions and holds.
When the cursor is positioned at a field with predetermined
parameters, these buttons cycle through the options. In fields with
predetermined numerical values, pressing Select increases the
value by one unit; pressing Select decreases the value by one unit.
Holding down a Select button increases (or decreases) the value
continuously. Press Enter or a cursor arrow button to confirm the
selected value.
The four cursor buttons move the cursor, in the direction of the arrow,
to the next entry field. If there is no changeable field in that direction,
the cursor moves diagonally or remains in its current location.
In most cases, after entering a new value in an entry field, pressing an
arrow button saves and/or executes the change. The exceptions are the
