Each ebro FOM 330 Oil Quality Tester must be adjusted to the specific oil used to ensure accurate measurements. Since each oil has different chemical properties, adjustment with fresh oil is necessary. This is explained on page 31 of the user manual, which is supplied with the Tester. Before the adjusment can get performed, settings of all relevant oil data need to get entered: Quick oil settings
Solution steps:
Preparation
- Make sure to use new and unused frying oil
- The oil temperature must be between 150 °C and 190 °C
- Before adjustment, the FRPC value for the fresh oil must be set correctly. Also other settings need to be adjusted if required (see 'Quick oil settings' on page 28)
- Perform a test measurement to preheat the sensor and speed up the calibration process
Quick oil settings
The Quick oil settings function allows fast and convenient configuration of all relevant parameters for the oil in use. This includes values for fresh oil, offset and gain correction, and signal thresholds.
Start Quick oil settings
- Press and hold the UP button for 5 seconds
- Options will appear one after another
- It is not possible to go back, but you can exit at any time using the ON/OFF button
- Each option can get adjusted using UP/DOWN, next with MENU
Configuration Options
- FRPC – Fresh Oil Value Should reflect the TPM value of the fresh oil
- OFSET – Offset Correction Set the desired offset value
- GAIN – Gain Correction Set the desired gain value
- LIM 1 – Yellow Signal Light Limit Value between fresh and medium-quality oil
- LIM 2 – Red Signal Light Limit Value between medium and old oil
You are then returned to the measurement mode.
Adjustment can get processed after oil setting is complete.
Adjustment procedure
- Switch on the device using the ON/OFF button
- Press and hold the DOWN button for 5 seconds until "CAL" appears in the display
