Two-clamp stakeless measurement (DET4TC2 and DET4TCR2)
Before making a stakeless measurement, please follow the procedures contained in the sections on
ICLAMP calibration.
1. Ensure the rotary selector switch is in the OFF position.
2. Connect the instrument as shown in Figure 35.

3. Close the ICLAMP around the conductor under test. Ensure the arrow on the side of the jaw is
pointing in the same direction as the arrow on the VCLAMP.
4. Close the VCLAMP around the conductor under test. Ensure the arrow on the side of the jaw is
pointing in the same direction as the arrow on the ICLAMP.
5. Ensure a minimum separation of 100mm between the ICLAMP and VCLAMP.
6. Set the rotary selector switch to the position.
7. DET4TC2 and DET4TCR2 only: Select the desired test frequency using the Hz button.
8. Press and release the TEST button [by holding the TEST button, the resistance measurement will
be continually updated].
9. The instrument will perform pre-measurement checks, the status of which will be indicated on
the display.
10. The stakeless resistance reading will be displayed as shown in Figure 36.
