As part of the routine annual maintenance of the IQT, the IQT’s user is expected to verify the calibration of the data acquisition board and adjust the settings if necessary. Since all the signals from the IQT’s instrumentation are connected to the data acquisition board, accurate measurements are only possible if it is properly calibrated. CFR Engines Canada’s Customer Kit for Data Acquisition Board Calibration provides a simple and convenient method of performing this calibration procedure.

Precise operation of the IQT depends on accurate and repeatable measurement of the instrument’s critical temperatures. The fuel injection pump, combustion chamber pressure sensor and injector nozzle coolant passage temperatures have the greatest effect on IQT accuracy. To ensure that these temperatures are within their required operating limits, the temperature readings must be verified using known temperature references. CFR Engines Canada’s Thermocouple Verification Kit provides a simple and convenient source of known temperature references, for use with these three temperature readings.

Precise operation of the IQT also depends on accurate and repeatable measurement of the charge and injection actuator air pressures. To ensure that these pressures are within their required operating limits, the calibration of the charge and injection actuator air pressure sensors must be verified annually. CFR Engines Canada’s Pressure Sensor Calibration Kit provides a simple and convenient method of performing this calibration procedure.
