Page 4: Overview
Overview Introduction Digi Cell Plus (DIGI+) is a Digital Oil Test Cell with USB storage and charging. DIGI+ provides an accurate means of detecting and measuring the quantity of water (H O) in oil and / or the residual Base Number (BN) of oil. This battery- operated, rugged and compact mobile instrument provides easily retrievable data to ensure fast, accurate and consistent management of lubricating oil samples. -
Page 5: Safety Information
Safety Information DIGI+ and reagents should be operated by persons trained in the use and handling of hydrocarbon products, including new and used lubricants. Persons should also be familiar with basic laboratory or workshop environments and associated hazard awareness. Prior to operating, DIGI+ should be inspected for damage. If any damage is found, consult with the supplier of DIGI+ accordingly. -
Page 6: Test By-Product
Test by-product (H Hydrogen gas (H Use in well ventilated areas. build-up risk No open flames, smoking or sources of ignition. Never add water instead of oil samples. Dispose of waste carefully. The water in oil test reagents react rapidly with water. In normal operation up to 70 ml H is generated. -
Page 7: Principle Of Operation
Principle of Operation DIGI+ measures the pressure generated by a chemical reaction that takes place inside the closed sample cup. An oil sample and reagents are put into the sample cup and DIGI+ is closed and shaken to aid the chemical reaction. The pressure is proportional to the parameter to be measured. -

Page 13: Sampling
Sampling Obtaining a representative sample is one of the most important parts of oil analysis. If a sample does not represent the true condition of the lubricant and component at the time of sampling, the reliability of both the test result, and the interpretation of it, is affected. -

Page 17: Cleaning
Cleaning Cleaning is required following each oil calibration and each test. The following steps should be taken to ensure safety: 1. Contents should be disposed of carefully. 2. DIGI+ body upper and sample cup (including agitator for H O testing) should be thoroughly cleaned. -

Page 20: Interpreting Results
Interpreting Results Water Water contamination may cause different problems in different types of lubricating oil, although corrosion is always directly associated with water ingress. Whatever the equipment, water can displace the oil at contacting surfaces, reducing the amount of lubrication and activating surfaces which may themselves act as catalysts for degradation of the oil. -
Page 21: Base Number
Base Number BN is only relevant to diesel engine lubricants and not relevant for gear oils or hydraulic oils. Alkaline additives are present to neutralise acids derived from both combustion (mainly strong sulphuric and nitric acids) and those weaker, organic acids resulting from oxidation of the oil as occurs during ageing. -

Page 29: Spid Measurement & Storage
SPID Measurement & Storage A SPID set is a batch of single tests. A new set is opened and then test results are collected. Measurements can be repeated, for example, with an H O measurement, if the test is below the detection limit and a lower range is needed (from 0.1 % to 20.0 % to a 0.02 % to 1.00 % range on the same SPID). -

Troubleshooting Measurement Symptom Possible Cause Possible explanation and Solutions In very rare cases, the water test reagents may react with a component of the stock oil. If DIGI+ continuously over- Reaction with the oil pressurises, yet the water content is known to be in range, the water test will not be suitable for use with that stock oil. -
