molbox RFM™ v1.20d Embedded Software

Run Winflash and select the file downloaded as the file to write to the product.

Make sure the correct COM port of the product is connected to a RS232 port on the host PC. Use a null modem cable to COM2 port of PG7000 Piston Gauge. Use a standard RS232 cable to COM1 port of PPC, PPC, RPM and molbox.

The updating of embedded software should only be performed after given specific instructions to do so from a Fluke Calibration Authorized Service Center.

If the update isn't performed properly, your product will be inoperable until it is.

Rev 1.20c (2011 Sept 28)
FIX RFM-135: When attached to molbloc-S, upstream pressures may glitch after rapid changes in pressure causing false pressure readings.
FIX RFM-134: Uncalibrated gases selected on the RFM should not use the enhanced features of the default N2 calibration
FIX RFM-131: Incorrect downstream pressure display.
FIX RFM-2: Pressure display was not flashing if pressure was out of REF7 enhanced molbloc calibrated range.
FIX RFM-1: When RFM is attached to REF7 Enhanced molbloc with downstream calibration, downstream pressure disappears from RFM display if out of molbloc calibrated range.

Rev 1.20b (2010 Feb 26)
FIX: Microrange DP is reading 9% less than non-microrange DP when upgrading from 1.10c or less to 1.20a.

Rev 1.20a (2010 Jan 5)
ADD: The #5 key (pressure & temperature display key) loops back to the current "run" screen after cycling thru the pressure and the temperature screens
ADD: Apply same tare limits used on manual tare to the "dynamic" tare when BPR is off (sonic bloc only)

Rev 1.20 (2009 Dec 16)
ADD: Able to read and operate with molblocs formatted for molbox1+ v6.00 (named calibrations, REFPROP gas data, etc.)
ADD: Add AUTOZ limits to the RFM
ADD: Add temperature adder and multiplier
CHG: VER and *IDN? Now reply "FLUKE"
FIX: Changes to the UL were lost on power cycle

Rev 1.10c (2009 Feb 20)
ADD: All molbox gases are now supported by the molbloc-S.
CHG: Improved N2 and Air gas properties used for molbloc-S.
FIX: Remote leak check now functions normally.
FIX: Leak check now uses a revised spec for a 1E5 molbloc if microrange is bypassed or the original spec if microrange is enabled. This avoids leak check false alarms.
FIX: FREEZE display setting is retained when RFM power is cycled.
FIX: CLEAN display setting is retained when RFM power is cycled.
FIX: Secondary password counter no longer resets when RFM power is cycled.

Rev 1.10b (2005 May 06)
ADD: New "OHMS" command to get the current measurement of the upstream and downstream molbloc PRTs
(in ohms).
ADD: New "STDRES" command to get the standard resistor values used for ohmic measurement circuit calibration.
ADD: New "RES" command to remotely set the molbox RFM flow display resolution
ADD: Remote responses use a fixed flow resolution of 0.001%FS (0.0001% if microrange is active)
CHG: Reply to the "TEMP" command now has separate up and down stream temperature fields.
CHG: Microrange feature now retains its previous state when the unit is powered off and then back on.
CHG: Microrange feature retains its previous state when switching from molbloc-L to molbloc-S and back.

Rev 1.10a (2004 Jun 24)
FIX: 'K' factor and flow adjustment adder/multiplier not being applied to molbloc-S flow measurements.

Rev 1.10 (2004 Jun 01)
ADD: Support of molbloc-S sonic nozzle based flow elements.
ADD: Support separate RPT pressure tares for molbloc-L and molbloc-S operation.
ADD: Disable head if enabled when in the RPT calibration "run" screen. Indicate this with a message when
entering the calibration menu.
ADD: RPT AutoZero function and supporting local menu and remote command
(same as molbox1).
ADD: Indicate if AutoZero is enabled in the calibration run screen.
ADD: Support of C4F8 under "Other gas".
ADD: Separate leak check settings for 1E5 and larger molbloc-L sizes.
ADD: Humidity ratio calculation, menu, and remote command for air when using molbloc-S (from molbox1).
ADD: Pressure head correction support including calculations, local menu, indicators and remote command
(from molbox1).
ADD: Bloc access to [SPECIAL], <4cal>, <3edit> and [SETUP], <6adj> when the security level is set to LOW.
CHG: Allow the Reynolds number indication to use scientific format if needed
CHG: Use the actual entered stability setting for Ready/Not Ready determination when micro-range is enabled instead of using 10 % of the entered value.
CHG: "!RANGE" command to harmonize with molbox1's.
CHG: RPT designators to SI style (same as molbox1).
CHG: Delay starting RPT pressure measurements until all PRTs are initialized.
CHG: A700K RPT (formerly A0100) UL and PMAX to 630 and 660 kPa absolute.
CHG: Revise and add to leak check settings to improve usefulness of molbox leak check.
CHG: Omit data from the first 10 sec of the second half of the system leak check to avoid using data from the transition condition.
FIX: Internal real time clock could not properly set the date past year 2009.
FIX: The 'K' that appears on the display to indicate an active K factor. Place it just after the flow units and ensure
it is blanked out when the K factor is disabled. Alternate the 'K' indicator with the 'A' used to indicate an
'adjustment' entry has been made.
FIX: A "Reset ALL" could result in a fatal exception with no way out of this condition.
FIX: '!BLOCCOEFn' and 'DEVICE' commands.
FIX: Display pressures after application of AutoZero in the calibration "run" screen.

Rev 1.00e (2001 Dec 07)
ADD: Pressure and flow display in the query between the first and second halves of the system leak check to allow user to verify stability before proceeding with leak check.
CHG: Operate the internal bypass valve at the end of the first half of the system leak check instead of the start of the second half to improve reliability of leak check using 1E1 molbloc.
CHG: Add an additional 10 second settle period to the beginning of the second half of the system leak check to improve leak check reliability.

Rev 1.00d (2001 Aug 16)
FIX: Avoid "CAL ERR" when a gas for which the molbloc is not calibrated is selected on the molbox.

Rev 1.00c (2001 May 16)
ADD: New gas, C2H2 (Acetylene). FIX: "Soft" power on/off indicator LED operation.
ADD: Improve pressure reading routines to eliminate occasional aberrant readings. FIX: "Previouse tare" field of the "TARE" remote query so that is shows the "previous tare" rather than '0' after using the remote "TARESETUP" comand.
FIX: Increase the purge time countdown field width to 3 digits.

Rev 1.00b (2000 Mar 06)
ADD: "XE" and "Butn" gas support.
CHG: Display molbloc ranges using new molbloc range identifiers using scientific notation.
CHG: Modify the "#" command to not have a timeout period. This command will send the Arg data only. If a reply is rcvd from COM2, it will be replied.
FIX: Ready the status in the reply to a "PR" or a "TARE" command would always return "R" instead of "R" or "NR".
FIX: Add missing comma that separates the 4th and 5th data fields in the "FRA" command reply and fix the reply flow resolution.
FIX: IEEE communication timeout if using a National Instruments IEEE card with automatic serial poll enabled.

Rev 1.00a (1998 Dec 18)
CHG: Update calculation of total flow when using totalizing display function.
FIX: The TOTAL remote command is accepted.
