• 0RGH configuration field
In this field you can select an option for temperature regulation of the water
jacket in the outer vessel. The following options are available:
( ) ,VRSHULEROLF DW ƒ& Measurement and calculation according to the
isoperibolic procedure. The temperature of the outer
vessel is 25 °C.
This mode can run with cooling water temperatures
of from 12 °C to 23 °C.
Standard value: 18 °C to 20 °C
( ) ,VRSHULEROLF DW ƒ& Measurement and calculation according to the
isoperibolic procedure. The temperature of the outer
vessel is 30 °C.
This mode is selected for cooling water tempera-
tures from 23 °C to 28 °C.
Standard value: 23 °C to 25 °C
The isoperibolic measurement procedure is suitable for the most demanding
levels of accuracy. The measurement time is 20 - 25 minutes/measurement.
( ) '\QDPLF DW ƒ& Measurement and calculation based on a shortened
dynamic procedure. The temperature of the outer
vessel is 25 °C.
This mode can run with cooling water temperatures
of from 12 °C to 23 °C.
( ) '\QDPLF DW ƒ& Measurement and calculation based on a shortened
dynamic procedure. The temperature of the outer
vessel is 30 °C.
This mode is selected for cooling water tempera-
tures from 23 to 28 °C.
The dynamic measuring procedures ensure measuring times of 7 -12 min-
utes/measurement with sufficient accuracy.
If the operating mode is changed or the calorimeter was not ready for operation,
the initialization dialog box appears after the 6HWWLQJV dialog box closes to make
certain that this mode can be implemented with the cooling water conditions that
have been provided.
• 5HI JURVV FDO YDOXH [J/g] configuration field
In most cases, certified benzoic acid is used. The required gross calorific value
should be entered. If you are working with different reference fuel, the gross
calorific value of this fuel must be entered here.
