GF3000 kWh Meter Test Bench

The GF3000 is a multi-position three phase energy meter test bench for laboratory testing of energy meters. The manufacturer's category page lists creeping and starting tests, influence-quantity and repeatability tests, and IEC/EN 60736 as a test reference. An ANSI version and a -G version are listed, the -G version adding EMC anti-interference metering tests, harmonic injection, no-load and unbalance tests.

The image on this page is a category illustration from the manufacturer's homepage, not a photograph of the GF3000 bench. No photograph of this bench is shown here, because the reference material behind this site does not tie a downloaded photograph to this model.

Item and specification

How to select

A bench suits a laboratory that tests many meters repeatedly, where a handheld reference meter would be too slow. The key selection questions are how many positions are needed, which voltage and current ranges the meters under test require, and whether the ANSI or -G test additions are needed. The manufacturer's category page does not give a position count for the GF3000 in the material behind this site, so ask for the position options and the current datasheet to be confirmed in writing before ordering.

Before payment, confirm the model and version, the position count, the voltage and current ranges, the quantity, and the delivery terms. No price, minimum order or lead time figure is stated here; confirm each in writing with your inquiry.

Records and comparisons

Keep a record for every test this instrument performs. A useful record states the instrument model, the device under test, the test settings, the results, the date, and the person who ran the test. Records of that form can be checked months later, when a result is questioned or a device is retested after repair. A record that only says pass or fail cannot be checked, and a test that cannot be checked will eventually have to be repeated.

When comparing this model with a neighbouring model from the same family, compare the same items for both: the test functions, the ranges, the accuracy class, the display and output features, and the standards referenced. A comparison that uses one model's headline figures against another model's detailed figures is not a comparison. Ask for the current datasheet for each model under consideration, and compare datasheet against datasheet.

If the instrument will be used by more than one person, agree who owns the test records and where they are kept before the first test. Shared instruments with private records produce results that cannot be checked by anyone except the person who ran the test, which defeats the purpose of keeping records at all.

What to confirm before ordering

Before payment, confirm the model, the specification from the current datasheet, the quantity, the price, the lead time, and the delivery terms, in writing. Ask in your inquiry to confirm the payment terms, the trade terms, and the reply time you should expect, rather than assuming any of them. No price, minimum order or lead time figure is stated on this site.

Notes

This page makes no claim that the bench or its laboratory is accredited to any laboratory standard. A listing phrase that a product is suitable for a laboratory standard is not an accreditation claim, and none is made here.
