Buying tips for handheld T&M equipments

T&M Markets or in general Manufacturing as an activity for any product, has become an activity which can be done anywhere in the so called Global Village wherever the Manufacturer gets Best Quality, adhering to his laid down Standards with lowest Cost of Production.

This has brought down cost barriers between Imported or Indian Made Product Pricing, & that is why over the past years, we have seen most of the Instrumentation specific Manufacturing JVs getting closed in India & benefits linked to CKD Kits have been coming down too to making even rework Manufacturing no more lucrative and thus most of Indian Brands turning to Relabelling and Importing instead of Manufacturing.

In Instrumentation, we believe Users productivity depends on equipment which delivers Lab Accuracy in handheld package and gives him confidence of using same in difficult environments of Field with Safety Best in Class & Ruggedness to last him.

With this, the product which fits his application and enhances his efficiency by delivering repeatable results is the need and thus User being aware of the benefits chooses a Product. Benefit that user gets from usage of good handheld T&M Products outweighs many fold over cost savings by a Sub standard Product purchase.

Before deciding on a product :

• Study your Application carefully which is bringing up Measuring/Calibration need.
• Make a wish list of features/capabilities & Accuracies / Repeatability you aspire.
• Understand your long term and short term Goals for using these Instruments.
• Understand specifications claimed by manufacturers properly, compare on same level field and ask for supporting / confirmations wherever in doubt of a claim from the Manufacture or even from Third Party Certification Agencies.

Consolidate requirements to get Quantity benefit of pricing and negotiate Training as part of the package or pay extra to ensure the investment made in T&M Instrumentation pays for itself by maximising usage by User Group. Under newly created TTL Knowledge Centre, we provide relevant Technology Trainings using Internal or External Faculty from the Industry in India. With globalization and swift progress, it has become vital to keep pace with the changing scenario to cater the needs and requirements of the world. We at TTL Knowledge Centre (TKC) facilitate customers, employees, retailers and channel partners cope up with their greatest challenge of unswerving growth by assisting them in understanding the key performance indicators for capitalizing on revenues and making them acquainted with the products.

TTL Technologies has skilled & equipped Service Centres with added Calibration facilities with NABL Accreditation too to assist buyers Post Sales.

Using Fluke DMMs for a Quick Check of Fuel Pressure on General Motors Vehicles

1. Place the test leads in the 10 amp position, and the function rotary switch in the DC amp position.
2. With the ignition switched "off," connect the red test lead to battery positive. Do
not let the black lead touch ground.
3. Connect the black lead to fuel pump test terminal. The test terminal is located on the end of about a 4" pigtail on the relay itself. This is typically located in the cowl area of the vehicle. *

Compare readings to chart below. Readings below are with the vehicle battery at 12.4 volts. A small spark is normal.

Fuel System Min-Max Fuel Pressure Normal Draw
TBI 9-13 psig 2-4 amps
PFI 36-41 4-6 amps
CPI 5 5-64 8-9 amps

Lower amperage than chart: usually a no start condition, or long cranking time.
· High resistance in fuel pump harness connectors
· Fuel pump ground, or fuel pump
· Out of fuel in tank
· Pump is cavitating from hot fuel
· Vehicle battery low.

Higher amperage than chart:
· Fuel filter restriction
· Fuel return line restriction

If amperage slowly rises after being connected, a fuel filter should be suspected. Allow pump to run for 30 seconds.

Common sense test: Before condemning any part, repeat the test above on a vehicle with the same fuel system and compare your readings
