[. . . ] RPM4/HPMS A70M/A20M-AFTM Reference Pressure Monitor with High Pressure Mounting System Operation and Maintenance Manual NSN 6685-01-529-6990 RN (2 of 3) © 2007 DH Instruments, a Fluke Company RPM4/HPMS A70M/A20M-AF OPERATION AND MAINTENANCE MANUAL High pressure liquids and gases are potentially hazardous. Energy stored in these liquids and gases can be released unexpectedly and with extreme force. High pressure systems should be assembled and operated only by personnel who have been instructed in proper safety practices. This instrument is not to be operated in any other manner than that specified by the manufacturer. © 2007 DH Instruments, a Fluke Company All rights reserved.

[. . . ] These functions are considered part of RPM4 maintenance and are covered in the maintenance section of this manual (see Sections 5. 2, 5. 3). 3. 5. 9 <9RESET> PURPOSE To reset various RPM4 settings to default or factory values. PRINCIPLE RPM4 stores its user definable settings in non-volatile memory. The reset menu allows the user to selectively or completely reset these settings to factory defaults. This clears any settings that the user has made, and should be used only to restore the RPM4 to a known state. RPM4 goes through its power up sequence after any type of reset is executed. RPM4 reset functions will change current settings to factory defaults. These may include settings vital to RPM4 operation and affecting the calibration of the quartz reference pressure transducers (Q-RPTs). Reset functions should only be used by qualified personnel with knowledge of reset consequences. Reset functions should never be used "experimentally". OPERATION To access the RESET menu, press [SPECIAL], <9reset>. The display is: RESET menu choices include: <1set> <2units> to reset general system operating parameters (see Section 3. 5. 9. 1). to reset unit of measure functions (see Section 3. 5. 9. 2). 1sets 2units 3ATest 4cal 5all <3ATest> to reset AutoTest parameters, clear File AutoTest files and clear the AutoTest data log (see Section 3. 5. 9. 3). <4cal> <5all> to reset internal calibration coefficients and modes (see Section 3. 5. 9. 4). to reset all settings except ID and security password to factory default values (see Section 3. 5. 9. 5). 3. 5. 9. 1 <1SETS> PURPOSE Sets most general operating parameters back to default values. Does not affect calibration coefficients, remote interfaces or AutoRange ranges. The Reset ­ Sets resets are itemized in Table 9.

[. . . ] This creates a pseudo Q-RPT designated HL. If the pressure measured by the Q-RPT exceeds Pmax!, an overpressure condition occurs. Pressure controller calibrator manufactured by DHI. RPM4 can be used as an external reference device for a PPC3. [. . . ]
