6.9 SWEEP Mode

For 4-pole earth measurements (without clamp, selective with clamp, or with the

GroundFlex

), it is possible to select the frequency sweep mode (SWEEP).

Press the Hz/OPTIONS button, then the ► button. The device then displays the

first free memory location (OBJ:TEST) in which to store a series of measurements

with a series of preset frequencies.

The device makes a measurement at each of the following frequencies:

128

256

513 1025 1465 2051 2539 3125 3516 4102 4687 5078

These SWEEP frequencies are factory defaults, preset in the memory. The user

can change them by configuring the tester using DataView

software.

In the manual mode, you can activate or deactivate the smoothing of the measure-

ment results by pressing the 2nd + DISPLAY (SMOOTH) buttons. This smoothing

consists in displaying an exponential mean value, a significant help with highly

fluctuating values.
