Fluke RPM4 manual SDS Self Defense System, Edit head height

3. OPERATION

OPERATION

To access the HEAD function, press [HEAD]. The display is:

Edit head height:

1.	Test fluid currently specified for the head correction.	+ 25	cm	N2
2.	Edit field for head height.

Edit the head height to the desired value. Press [ENT] to return to the MAIN RUN screen with the new head correction active. Press [ESC] to return with no changes.

The reference height of the RPM4 pressure measurement is the middle of the RPM4 TEST port. The head height should be entered as a positive value if the device or system under test is higher than the RPM4 and negative if it is lower.

The HEAD function is NOT range specific. The HEAD ON or OFF status remains the same as Q-RPTs and ranges are changed. Edits made to the head settings are independent of active range or Q-RPT.

When a head correction is being applied, it is indicated by <h> in the top line of the MAIN RUN screen (see Section 3.1.1). When the head correction is zero, the <h> is not shown.

To change units of head height between inches and centimeters and to change the test fluid species, use [SPECIAL], <3head> (see Section 3.5.3).

3.3.8 [SDS] (SELF DEFENSE SYSTEM)

PURPOSE

To CLOSE SDS on all reference pressure transducers (Q-RPTs). To OPEN SDS on the active Q-RPT.

SDS is present only on Q-RPTs designated A7M or lower.

The [SDS] key should be used with care to avoid accidentally overpressuring a Q-RPT. Always double check to ensure that the pressure applied to the Q-RPT’s TEST port is lower than the Q-RPT’s maximum pressure before OPENING SDS.

SDS can be set to permanently be OPEN as if no SDS were installed (see Section 3.5.4.2).
