Diagnostics, Calibration, and Troubleshooting Electronic Calibration (E-CAL) Adjustment for E-85/DEF Unit
Calibration and Accuracy Checks - DEF Dispensers
The settling time for freshly dispensed DEF is longer than for gasoline or diesel.
Therefore, a three-minute wait time between dispensing the DEF into the prover can
and taking the reading from the sight glass is recommended.
IMPORTANT INFORMATION
Units must be properly purged before calibration or calibration verification. Incomplete
purging of air can result in inaccurate calibration or errors in calibration verification
testing.
IMPORTANT INFORMATION
A stainless steel prover can must be used to calibrate DEF. Do not use a can that has
been used for other fluids. Contaminated DEF can cause damage to vehicle engines,
contaminated fuel can corrode dispenser material(s), vehicle catalytic converter(s), or
damage vehicle engines.
CAUTION
An ELAFIX 40 Magnetic Adapter (M10656B001) must be pushed over the spout when you
dispense DEF into the prover can during calibration or service.
Each time a meter is calibrated, a volume of DEF is generated. This DEF must be properly
managed and cannot be discarded into the storm drain or where it can possibly reach surface
water or groundwater. If the DEF is to be returned to the supplier, store it in a closed

leak-proof container.
Avoid dispersal of spilled material and runoff. Ensure that DEF does not come in contact with
soil, waterways, drains, and sewers. Inform the relevant authorities if the product has caused
environmental pollution (sewers, waterways, soil, or air).
DEF poured back into the tank must be kept clean. Do not allow DEF to become contaminated
during handling.
