Digital Dynamometer Control Instrument Model 1054

The Model 1054 Dynamometer Control Instrument is designed for use with any Vibrac Dynamometer with digital speed option.

This instrument contains a 4-1/2 digit readout for torque and a 5 digit readout for speed. Large (0.5 inch) characters provide for easy viewing.

A linear ramp, and ramp rate adjust, enables the instrument to control the load brake during a test cycle. The ramp is activated by the push of a button at which time the load will be increased from a minimum to a full load. By controlling the rate at which the load is applied, inertia induced errors can be minimized.

A peak detection circuit is provided for capturing peak torques.

The front panel selector switch ranges the instrument for use with the selected Vibrac Dynamometer.

One front panel control knob enables the user to zero the transducer. This process automatically establishes the span or calibration of the transducer to the instrument.

A 0 to 10 volt analog output proportional to the torque and speed is supplied on the rear panel for use with the auxiliary equipment including PC software applications, oscilloscopes and XY plotters.

A remote option package is available to facilitate external computer control of the instrument (consult factory for additional information).

Readout Instrumentation

FRONT PANEL DESCRIPTION

TORQUE READOUT — The 4-1/2 digit readout is scaled to read torque in direct engineering units or in percent full scale.

PEAK — The lighted push-button switch, when engaged, will display peak torque and speed from the internal peak detecting circuits.

RESET — The lighted push-button switch, when engaged, will reset the peak holding circuits.

HOLD — The lighted push-button switch, when engaged, will hold or latch the displays

SPEED READOUT — The 5 digit readout is scaled to read speed in RPM.

POWER — System power switch.

STALL — The lighted push-button switch, when engaged, will apply full load to the device under test.

RAMP RATE — For setting the rate at which the load will be applied.

OFF — The lighted push-button switch, when engaged, removes power from the load device on the test head.

ADJUST — The ten turn potentiometer is for manually adjusting the load to the device under test.

TORQUE — The lighted push-button switch, when engaged, selects the manual torque load control and engages the torque set potentiometer

ZERO ADJUST — For setting the proper zeroing voltage for the transducer that is connected to the instrument.

TRANSDUCER SELECTOR — The thumb wheel switch is for selecting the proper ranging and the desired display units for the transducer that is connected to the instrument.
