5. BASIC OPERATION
Before Use
1. Verify that the serial number on the instrument and the calibration chart are
the same, since readings may vary among instruments.
2. Check that the calibration and certification are current.
3. The Memory Lock feature should be OFF (pushed down). (See “Memory Lock
Feature” below.)
4. The pointer must be resting at 0 on the dial. If it is not, the calibration should
be checked. (See “Checking Accuracy” in Section 6 below.)
Selecting the Riser
1. Determine the diameter of the cable to be checked. (See Figure 3)
