• The Model 1054 Dynamometer Control Instrument is designed for use with any Vibrac Dynamometer with digital speed option.
• This instrument contains a 4½ 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 INSTRUMENT

Front Panel Description

1. TORQUE READOUT – The 4½ digit readout is scaled to read torque in direct engineering units or in percent full scale.
2. PEAK – The lighted push-button switch, when engaged, will display peak torque and speed from the internal peak detecting circuits.
3. RESET – The lighted push-button switch, when engaged, will reset the peak holding circuits.
4. HOLD – The lighted push-button switch, when engaged, will hold or latch the displays
5. SPEED READOUT – The 5 digit readout is scaled to read speed in RPM.
6. POWER – System power switch.
7. STALL – The lighted push-button switch, when engaged, will apply full load to the device under test.
8. RAMP RATE – For setting the rate at which the load will be applied.
9. OFF – The lighted push-button switch, when engaged, removes power from the load device on the test head.
10. ADJUST – The ten turn potentiometer is for manually adjusting the load to the device under test.
11. TORQUE – The lighted push-button switch, when engaged, selects the manual torque load control and engages the torque set potentiometer
12. ZERO ADJUST – For setting the proper zeroing voltage for the transducer that is connected to the instrument.
13. 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.
