  • Page 32: Function And Operation

    Chapter 2 Function and Operation Measurement Configuration Most measurement parameters are user-defined. Changing a measurement parameter will change the measurement precision and speed, as well as the input impedance. An appropriate measure- ment parameter based on the actual application will ensure faster measurement or higher mea- surement precision.
  • Page 33 T3DAQ1-16 User Manual Range T3DAQ provides auto and manual range selecting modes. In auto mode, the DAQ selects a proper range automatically according to the input signal. In manual mode, you can use the front panel key or menu key to set the range. The auto mode can bring a lot of convenience for users while the manual mode provides higher reading precision.
  • Page 34 The integration time applies to DCV, DCI, 2WR and 4WR measurements. T3DAQ1-16 expresses the integration time by the number of power line cycles, the unit is PLC. The DAQ automatically detects the input power line frequency at power-on. If the frequency is 50Hz, the integration time can be set to 0.005PLC, 0.05PLC, 0.5PLC, 1PLC, 10PLC, 100PLC and the...
  • Page 35 T3DAQ1-16 User Manual 2. In ACV, ACI ,FREQ/PERIOD measurements, the resolution is fixed at 6½ digits. 3. In CAP measurements, the resolution is fixed at 4½. 4. The instrument always displays 2 digits after the decimal point in CONT measurement.
  • Page 36 T3DAQ1-16 User Manual DC Impedance DC impedance applies to DCV measurements. The default is “10MΩ”. In the range of 200mV, 2V or 20V, you can choose “>10GΩ” to reduce the loading error on the measured object, caused by the multimeter load.
  • Page 37 T3DAQ1-16 User Manual Auto Zero Auto zero (Auto Zero) applies to DCV, DCI, 2WR and 4WR measurements. Enter the specific measurement function and press [Auto Zero] in the menu to perform the setting, as shown in diagram below (take DCV measurement for instance).
  • Page 38 AC Filter AC filter applies to ACV and ACI measurements. It can optimize the low frequency accuracy and minimize the AC settling time. T3DAQ1-16 provides three types of AC filters (>3Hz, >20Hz, >200Hz). The AC filter to be used is determined by the input signal frequency. You should generally select the highest frequency filter whose frequency is less than that of the signal you are measuring, be- cause the higher frequency filters result in faster measurements.
  • Page 39 T3DAQ1-16 User Manual Short-circuit Resistance This function only applies to a continuity test. When the measured circuit has a resistance lower than the short-circuit resistance, the circuit is considered as connected and the beeper sounds (if sound is on). The default short-circuit resistance is 50Ω and the setting is stored in non-volatile memory.
  • Page 40 T3DAQ1-16 User Manual Gate Time Gate time (also called Aperture Time) applies to the FREQ / PERIOD function. It decides the res- olution of a low-frequency measurement. The longer the gate time, the higher the resolution of the low-frequency measurement and the slower the measurement, and vice versa.
