ISO 121516-1
ASTM D6079 60°C
ASTM D6079 25°C
GASOLINE
Description
Measurement of Diesel Fuel Lubricity
Diesel fuel - Assessment of lubricity using the high-frequency
reciprocating rig (HFRR)
Standard Test Method for Evaluating Lubricity of Diesel Fuels
by the High-Frequency
Reciprocating Rig (HFRR)
Standard Test Method for Evaluating Lubricity of Diesel Fuels
by the High-Frequency
Reciprocating Rig (HFRR)
Test procedure at 25°C suitable for testing gasoline
From the main menu NEXT and PREV cycle through the list of standard tests.
Setup menu 1
Setup menu 1 consists of options to calibrate the HFR.
The stroke, force and film calibration are fully described in the calibration section.
Setup menu 2
Setup menu 2 also consists of options to calibrate the HFR.
The main and alarm temperature calibration are fully described in the calibration section.
Setup menu 3
The time, date and printer setup options are accessed from the setup 3 menu. The printer option relates to the mini printer option and cannot be connected to a standard PC printer.
Time & Date
The time uses the 24-hour clock format.
Press + or - to adjust the hours, then press -> to adjust the minutes. The seconds are not adjustable. The date is set in the same manner. Note that the date uses international format (day/month/year).
Printer
The PRINTER option is used to install and test the mini printer.
Setup menu 4
The HCFs (humidity correction factor), RH/T (relative humidity/temperature) and defaults options are accessed from the setup 4 menu.
HCFs
If using a test method that requires the humidity correction factor to be applied, this option will alter the value relating to the high, low or unknown fuel type..
RH/T
An optional combined humidity and temperature probe can be connected to the rear of the electronics unit. For some test procedures the wear scar must be adjusted to compensate for the effect of fuel moisture content on the result. The probe will automatically measure the ambient temperature and humidity at the start and end of the test, instead of the user have to make the measurements manually.
If connected, the relative humidity/temperature probe will display the ambient temperature and relative humidity in place of the clock on the 'READY' screen.
It's operation can also be checked using the RH/T option from the 'SETUP4' menu. If a relative humidity/temperature probe is connected as screen similar to the one below will be shown:
If the probe is unplugged or becomes faulty, the following message will be shown, and tests will have be manually measured and entered into the HFRR at the beginning and end of the test.
Defaults
This option resets the factory defaults of the control unit. By pressing ok from the defaults menu it will restore all the calibration values to the factory defaults. Once the factory defaults have been restored, a full calibration will be necessary.
Info
A summary of the last 50 tests is stored in the instrument's flash memory. By selecting HISTORY from the 'INFO' menu will show a summary of the test history.
Each test history is displayed on 3 screens:
DETAIL1
DETAIL2
DETAIL3
If a mini printer is connected, the 'DETAIL3' screen will also have a PRINT option to print a test report for reference.
