QuadTech 1730T - Operation; Speed and Accuracy

Operation 150821/A4 Page 41 of 110
2.4.5 SPEED/Accuracy
Trading accuracy for speed, program the measurement speed of the 1730T instrument to Slow
(3measurements/second), Medium (22 measurements/second) or Fast (66 measurements/second).
The basic LCR accuracy (0.1%) and D accuracy (0.001) are specified for the slow measurement
speed. In MEAS DISPLAY (Pg 2/3) press [F2] so that the MEDIUM box is highlighted. Use
the up arrow [⇑] key to increase the speed or use the down arrow [⇓] key to decrease the speed.
The instrument default setting is MEDIUM (22 meas/second).

The accuracy of the 1730T instrument depends on the speed of the measurement. Basic
Accuracy for LCR is ±0.1% and basic accuracy for DQ is ±0.001. Basic accuracy is specified for
the speed equal to 3 measurements/second, temperature = 23°C ±5°C, relative humidity (RH)
≤90%.
Table 2-4 lists the basic accuracy for ⏐Z⏐ - θ. For measurements made in fast mode double the
accuracy listed in Table 2-4.
