HFRR/HFR2 High Temperature Option (Part code: HFRHTO)
Overview
The HFRR high temperature option is used for testing specialised lubricants that allows tests to reach temperatures up to 400°C. All HFR systems can be used with the high temperature option although AutoHFR software is required for operation. Applications for the High Temperature box are shown in the HFRR application section.
The high temperature option is connected between the electronics/control unit and the HFR mechanical unit, as shown below.

Operation
HFRR Operation (Serial Number D500 Onwards)
In order to carry out a high temperature test, the heater box must be switched on before the test is started. Start the AUTOHFR software in the normal manner, as described in the AutoHFR section. At the 'Test Setup' stage, ensure that the 'Use High Power Box' option is selected.

Below this temperature, the box is not required and should remain off (although for convenience it can remain connected).
The operator will be prompted to switch on the high power heater box if the test temperature is over 150°C. At temperatures between 100 and 150°C a warning message will be shown, indicating that the high power heater box may be required.
If the HFRR instrument and high power heater box is manufactured after May 2004, the AutoHFR software can automatically detect whether you have the heater box attached. If the heater box is switched on then the AutoHFR software will automatically ensure that the 'High Power Heater' tick box on the start screen is enabled.
HFR2 Operation (Below Serial Number D500)
The high temperature control box is only required for testing at temperatures above 120°C (Standard 15 Watt heater configuration). Below this temperature, the box is not required and should remain off (although for convenience it can remain connected).
For users wishing to reach temperatures up to 160°C then 40 Watt heater conversion may be more suitable.
In order to carry out a high temperature test (i.e. above 120°C), the heater box must be switched on before the test is started. Start the AutoHFR software in the normal manner. At the 'Test Details' stage, ensure that the 'Use High Power Heater Box' option is selected, as shown below.
