Protimeter Speedy

Troubleshooting

Use the following procedures to troubleshoot suspected inaccurate results.

Suspected Low Reading

If the Speedy gauge readings are lower than you expect or anticipate, check the following:

• Was the test procedure followed correctly? Ensure the correct sample weight is used, the sample is placed in the Speedy

vessel, and the calcium carbide reagent is placed in the Speedy cap. Also, make sure the Speedy vessel and cap are united

and sealed in the horizontal plane to prevent premature contact of the reagent and sample.

• Was there was adequate cleaning of the Speedy vessel and cap between tests? Ensure all residues from previous tests have

been removed from the cap and vessel before starting a new test.

• Was sufficient reagent used? Repeat the test using an additional scoop of reagent.

• Was the reagent ineffective? Ensure that the reagent is fresh.

Note: The color of fresh reagent is dark gray; ineffective reagent that has been exposed to moisture in the air or other

sources will have turned light gray in color.

• Was sample preparation or sample-reagent mixing adequate? Consider grinding the sample prior to weighing and/or (for

Large Speedy only) using pulverizing balls.

• Was the temperature too low? Low readings may be recorded if the Speedy is used in very low temperatures. Take

numerous readings in quick succession to raise the operating temperature of the Speedy.

• Was there a pressure loss? Visually check the cap washer for signs of holes or leak paths. Remove the pressure gauge and

visually check the pressure gauge washer. Visually check the Speedy vessel and cap for hairline cracks.

• Is the pressure gauge defective? If the needle does not sweep smoothly across the scale plate, replace the gauge or return the

Speedy tester to an authorized distributor for service.

Suspected High Reading

If the Speedy gauge readings are higher than you expect or anticipate, check the following:

• Was the correct sample weight used? Ensure that the sample weight is weighed correctly.

• Was the gauge read correctly? Ensure that the Speedy is held in the horizontal plane at eye level when reading the pressure

gauge.

• Was the temperature too high? High readings may be recorded if the Speedy is used in very high temperatures. If the

Speedy is warm/hot to touch as a result of taking many readings in quick succession, allow time for it to cool down before

taking more tests.

• Is the pressure gauge defective? If the needle does not return to zero after releasing the pressure from the Speedy, replace

the gauge or return the Speedy tester to an authorized distributor for service.

Recommended Spares and Consumables

It may be wise to consider having the following spares and consumables available when using the Speedy tester, especially in

remote locations:

• batteries for the electronic scale, AA/LR6 1.5V (3 required)

• Speedy cap washer

• pressure gauge washer

• pressure gauge (note the measurement range)

• cleaning brushes

Other spares parts for the Speedy vessel are available on request.
