External Power Supply
Plug the provided transformer to charge the internal batteries in the unit.
RS 232 Connection:
The RS 232 can be used for printing or downloading torque values into a computer or used
with an external PC to calibrate the unit.
Rate: 19,200 BPS
Output Format: 8 bits fixed, 1 stop bit, no parity.

P O W E R T O O L T E S T I N G
The run down adapters (RDA) are designed to provide consistent and reliable torque readings for use with power driven
torque control tools. The RDA’s reduce the impact and irregular peaks that cause poor repeatability. Each RDA has an
effective torque range and will supply repeatable torque data within that range if used correctly.
Always use a quality joint rate simulator (run down adapter) when testing power tools in a simulated application. Use the
peak mode. The Peak mode is designed to meet the demanding frequency requirements for testing dynamic torque
applications.
Using Run Down Adapters
The EZ-TorQ includes a 1/4 Female Hex Square Drive Adapter which is used for testing hand tools. It also includes a
Run Down Adapter
Operation
1.
The run down adapter is placed in-line between the tool drive and transducer of the torque tester.
2.
The torque tester should be properly secured on a solid surface or a test bench.
3. Before each test run, the Input drive run down adapter (RDA) should be completely backed-up. (Unless using
Mountz AURA run down adapter)
4.
The RDA is designed to run in clockwise direction only.
5. Apply torque until RDA is run down completely. Then note or save reading with the torque tester.
