Troubleshooting

 

Measurement 

BN-specific Measurement

Symptom

Possible Cause

Possible explanation and Solutions

Over-pressure warning

Reaction with the oil

In very rare cases, the water test reagents may react with 

a component of the stock oil. If DIGI+ continuously over-

pressurises, yet the water content is known to be in 

range, the water test will not be suitable for use with that 

stock oil.

Incorrect volume of oil

All test ranges need different volumes of oil sample and 

reagents. Using too much oil can give too high pressure. 

Re-test and note volume of oil for the test. Ensure        

on-screen instructions are followed.

Oil contains more water 

than range

Retest on 0.1 % – 20.0 % range.

Possible gross water leak

Retest on 0.1 % – 20.0 % range.

Graph shows pressure 

loss 

Leak

Dirt on seal. Seal should be removed, cleaned thoroughly 

and replaced before retesting.
DIGI+ has not tightened properly. DIGI+ should be opened 

and re-closed, tightening by hand 1/8 turn only after the 

sample cup makes contact with the seal. 

 

Tools should not be used to tighten DIGI+.

Screen does not:

a) respond to button press

or

b) sleep after 5 minutes

Reset required

should be pressed together for 8 seconds.

Symptom

Possible Cause

Possible explanation and Solutions

Unable to calibrate BN

Oil has ‘non-Calcium’ 

BN additive.

The BN reaction requires oils to have established and 

conventional Calcium carbonate additives. 

Ca

2+

 alternatives do not react in the same way.

Pressure leak

Before starting the calibration, the insides of DIGI+ and 

sample cup must be clean and dry (particular attention 

should be paid to the O-ring and threaded surfaces).

BN used oil is reading 

higher than new oil

Contamination of oil

Cylinder oil leaking into system oil on 2-stroke 

diesel engine.

Wrong top-up oil used

Higher BN oil used to top up or incorrect oil added           

to system.

Wrong amount of oil 

tested

On high BN, only 2 ml of sample is needed. Care should 

be taken to put exactly 2 ml into the sample cup. 
All test ranges need different volumes of oil sam-ple and 

reagents. Using too much oil can result in too high 

pressure. Note volume of oil before re-testing.
