Function

Sets the drip rate for the pump-on mode. Choose only one toggle switch, and push it up to the desired dpm value.

These switches are set according to the section "Setting Normal (pump on) Mode Drip Rates", starting on page 16.

A two-digit display shows the drip rate count

Flashes every 12 seconds for timing purposes. You can count the number of drips seen during this 12-second interval and multiply them by five to arrive at the dpm rate.

This LED is useful when you want to quickly stabilize the drip rate by pressing the Open Valve (SW16) or Close Valve (SW18) push button.

Lights to indicate the six-second freeze interval. During this interval, which occurs once per minute, the needle valve may be opened or closed in order to adjust the drip rate.

Controls the two-digit numerical display:

In the down position (recommended):

When pump is on, displays the last minute drip count for a period of six seconds. The display goes off until the next minute drip count is displayed. When the pump is off, the display remains off.

In the up position (used for factory tests only).
