When single-coil absolute probes are connected to the BNC connector, it is important
to set the NORTEC 600 accordingly. Repeatedly press the MAIN FILTER menu key
( ) until the SPECIAL menu page is displayed. Set the PRB CONN parameter
(B key) to BNC with the knob. It is also recommended to set the low-pass filter to
100 Hz: press the MAIN FILTER menu key ( ) twice, and set LO PASS (B key) to
100 Hz using the knob.
2. Place the probe coil on the reference standard between two notches, with the
notches facing up, and then press and hold the A-LIFT NULL key ( ) on the
NORTEC 600 to activate the automatic lift-off function.
After a brief moment, the NORTEC 600 beeps and displays LIFT PROBE at the
top of the screen. When this text is displayed, lift the probe into the air, and wait
for the message to disappear.
3. Repeat step 2 until you become familiar with the automatic lift-off function.
It may take some practice to obtain the proper timing with the automatic lift-off
function, but once mastered, this function will help you obtain a faster calibration.
4. Place the probe between two notches on the reference standard again, press the
A-LIFT NULL key ( ), and then, after the nulling operation is finished, scan the
standard.
The screen should resemble the image shown in Figure 5-3 on page 123.
