[. . . ] Operation and Maintenance Manual PPCH-GTM High Gas Pressure Controller/Calibrator © 2007 DH Instruments, a Fluke Company 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.

[. . . ] PPCH-G goes through its power up sequence after any type of reset is executed. PPCH-G reset functions will change current settings to factory defaults. These may include settings vital to PPCH-G 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 not be used experimentally.

The display is: RESET menu choices include: <1set> <2units> <4cal> <5all> to reset general system operating parameters (see Section 3. 5. 4. 1). 1sets 2units 3ATest 4cal 5all <3ATest> to reset AutoTest parameters and clear the AutoTest data log (see Section 3. 5. 4. 3). to reset internal calibration coefficients and modes (see Section 3. 5. 4. 4). to reset all settings except ID and security password to factory default values (see Section 3. 5. 4. 5). 3. 5. 4. 1 <1SETS> PURPOSE Sets most general operating parameters back to default values. Does not affect calibration coefficients, remote interfaces or AutoRange ranges.

Sets the user defined unit to 1. 000/Pa (see Section 3. 5. 6). © 2007 DH Instruments, a Fluke Company Page 76 3. OPERATION 3. 5. 4. 3 · · <3ATEST> PURPOSE Resets Quick Test and Q-DUT Tests to default (see Section 3. 3. 6). Clears AutoTest data log (see Section 3. 4. 5). 3. 5. 4. 4 <4CAL> PURPOSE The Reset - Cal function will reset Q-RPT, utility sensor and barometer calibration coefficients and settings and reset AutoZ values to zero. This will change the PPCH-G calibration and could cause it to make out of tolerance measurements. Clears all user values affecting the calibration of Q-RPTs, utility sensor and the on-board barometer.

Combines all resets in one global reset command that clears the entire user section of non-volatile memory returning PPCH-G to the "as delivered" condition except the ID function (see Section 3. 5. 5. 4) and the security level password (see Section 3. 5. 5. 5).
