isolate and vent the specified Q-RPT.
Opening SDS with a pressure greater than Pmax! applied to the test port
may cause overpressure damage to the Q-RPT.

OPERATION
See
Section
3.2.8 for complete information on RPM4’s SDS (Self Defense
System) feature.
Turning SDS “full time OFF” eliminates normal SDS operation so that the
active TEST port remains open. However, the SDS overpressure function
(see Section 3.4.4.1) remains active.
To turn SDS full time ON/OFF, press

If
<2off>
is selected and SDS is not already open, the SDS opening screen with
indication of the maximum pressure of the Q-RPT is displayed. This is the same
screen used when opening SDS using the
[SDS]
key (see Section 3.3.8). Check
that the pressure applied to the Q-RPT module
TEST
port does not exceed the
Pmax! value before confirming that SDS should be opened.
Opening SDS with a pressure greater than Pmax! applied to the TEST port
may cause overpressure damage to the Q-RPT.
With SDS “full time OFF”, when using parallel measurement, the active TEST
port is still switched between the Ps and Pt port depending upon
measurement mode (see Section 3.2.5).
