Vanguard Instruments TRM-40

 VAN-TRM-40 40A Winding Resistance Meter with Auto Demagnetization

The TRM-40 is designed specifically to measure DC resistance values of
transformer windings, rotating machine windings, or any dc resistance of an
inductive device.

The TRM-40 has dual resistance-reading input channels that can measure two
winding resistances simultaneously (the primary and secondary windings of a
transformer). It can provide a fast and stable reading of very large
transformers by utilizing a 60Vdc power supply. The TRM-40 is capable of
outputting a selectable test current from 1A to 40A.

Computer Interface:
The TRM can be connected to a PC via the unit's RS-232C, USB, or Bluetooth
interface. The included Windows-based Transformer Winding
Resistance Analyzer (TWRA) software can be used to retrieve test records
(stored in the TRM or on a USB Flash drive) or to run tests from the
PC. Test records are automatically exported to PDF, Excel, and XML formats.

Resistance Reading Range - TRM-40: 1 micro-ohm 500 ohms
Test Voltage 60Vdc charging, 18V DC max during measurement

Accuracy: 1-19,999 micro-ohms: 0.5% reading, 1 count;
20-999 milli-ohms: 1% reading, 1 count;
1-2000 ohms: 1.5% reading, 1 count
