The Bantam is very versatile yet simple to operate. All test functions, including series and element tests, are controlled from front panel switches without the need for re-wiring. Bantam can support a large range of meter forms both transformer rated or self contained.
The handheld controller automates testing with the ability to automatically calculate, display, and store test results. Test quickly and accurately the first time to site. Automatic test and data storage eliminates operator error and reduces return visits.
Bantam’s ability to more fully test meters on-site will help reduce meter inventory maintained by utilities. Bantam allows the user to maintain a released version of test procedures for any specific meter manufacturer, model or meter form.
Packaged in the latest lightweight polymer alloy. Bantam is designed to withstand the rigors of everyday field use while delivering the accuracy you have come to expect from a Radian product.

Bantam is designed with portability and safety in mind. Packaged in high technology composite PVC/Acrylic alloy to help reduce weight yet maximize structural integrity. Should misconnection occur Bantams’ quick wiring safety check determines and prevents operation if voltage is detected on the current inputs. Furthermore, the 600V rated ON/OFF switch isolates the load from the meter service voltage to prevent flashover from occurring while connection to the test meter takes place.
The Radian RB-10 Bantam Lite is very versatile yet simple to operate. All test functions, including series and element tests, are controlled from front panel switches without the need for re-wiring. FL and LL test currents are logically placed on the current selection switch and the output current can be linearly adjusted from no load up to full range. Both unity (1.0) and 50% (0.5) lagging power factors can be tested. The hand held controller automates testing with the ability to automatically calculate, display, and store test results. The data can then be easily uploaded to a PC or printed on the RM-RPP portable printer.
Building on proven design with a long service record, this test solution is reliable and rugged. And the Bantam is built using patented circuitry with safety being a priority. The closed front design and remote handheld data collection exceeds the minimum safety requirements when in operation. Although the test kit is the first in a family of products, it is designed with the future in mind. The unit is future proof, upgradable to new innovations as they occur within the product family.
The accuracy of Bantam Lite is maintained using a choice of an embedded Radian RD-20 or RD-21 Reference Standard. Select the Standard that meets your budget and provides the accuracy necessary to adequately test the Energy meter workload.
For added confidence, and before transporting Bantam Lite on-site, the test kit can be easily hooked up to an external cross check Radian Reference standard. Using the supplied handheld comparator you can quickly and automatically determine if Bantam Lite is functioning correctly. This convenient cross check process is simple to operate and takes less than 5 minutes to run.
The Bantam Lite comparator/controller automates meter test calculations to help improve test efficiency, maintain measurement repeatability and record and store test data.
Bantam allows the user to maintain a released version of test procedures for any specific meter manufacturer, Model or Meter Form. Using the supplied RB-10-Link software installed on a remote PC, not only can you back-up the stored test data, but also develop or edit meter test procedures and later transfer to one or more Bantam Lite.
Centralize test procedures as well as measurement records are easy to manage with the Bantam solution. With the supplied software an appointed authority within your organization is given responsibility for creating/editing and distributing meter test procedures to test systems in the field. Furthermore, meter test records can be transferred to the software for later integration to a centralized database of your choosing.
