RKI Instruments GD-70D Series - Flow Rate Default Set 2-5

- 111 - GD-70D
<Flow Rate Default Set "2-5">
Regardless of whether the flow rate is manually or automatically set, when the reading on the flow rate
indicator is incorrect (due to aging degradation, improper flow rate default set, or other reasons), it must be
set to provide the right flow rate.
To set the Flow Rate Indicator, prepare and connect a flow meter (which indicates 0.5 L/min precisely),
and perform the default set with the flow meter while it is indicating 0.5 L/min.
