DeFelsko PosiTector 6000 v.3.0 - Manual (Page 4)

If a reading is still not obtained, dashes ( -- -- -- -- -- )
appear on the display.
Non-Ferrous Lock (N LOCK?)
Select the N LOCK? menu option (non-ferrous lock) when
operating regularly on non-ferrous substrates. This disables
the automatic substrate determination ability and forces the
probe to only use the eddy current principle when
measuring, regardless of the substrate. This shortens
measurement time and extends battery life.
TIP: N LOCK is also useful in instances such as measuring
paint on galvanized (zinc coated) steel. In AUTOmatic
(normal) mode the probe measures both the paint and zinc
over the steel using the magnetic principle. N LOCK
makes the Gage measure the paint over the zinc only.
TIP: Select N LOCK to measure over slightly magnetic
substrates; i.e. clear-coat on gold over nickel plated brass.
Although the probe’s magnet is used for the magnetic
principle, it is also used in N LOCK to magnetically
saturate a slightly magnetic substrate and allow the eddy
current principle to operate unhindered.
WARNING. With N LOCK engaged it is possible to obtain a
reading when measuring non-conducive coatings on steel.
Eddy current is not the preferred measuring principle on
steel.
Select the FN AUTO? menu option to return the probe to its
auto selecting capability.
Inch/Metric Conversion
Selecting the MILS? or MICRONS? menu option converts
the display and all stored readings from inch to metric or
vice versa.
Flip LCD
The FLIPLCD? menu option causes the display to read
upside down. On Separate Probe Gages this feature
allows the Gage to be laid on a work table with the LCD
conveniently pointed toward the operator, thus freeing the
operator’s hands to hold the probe and part to be
measured. On Built-In Probe Gages this feature is useful
when the Gage is used upside down to measure on a
ceiling.
Statistics Mode
Standard(2) and Memory(3) models only
When STAT ON? is selected, a symbol and a counter
(n 0) appear on the display. As each measurement is taken,
the reading is displayed and the counter is increased. An
incorrect reading can be removed by pressing
∅ before
another reading is taken. After a desired number of
readings, lift the probe from the surface and press
⊕ to
display statistics. Example:
mils microns
average: x = 1.8 x = 46
Standard deviation: σ = 0.5 σ = 13
number of readings: n = 3 n = 3
These statistics will be displayed until:
• the Gage powers-down.
• another reading is taken, in which case the sequence
starts over.
• any button is pressed, in which case the last reading is
displayed.
H I L O M ODE must be off to activate S TATISTICS M ODE .
Calibration adjustments cannot be made while in S TATISTICS
M ODE . To turn S TATISTICS M ODE off, select STATOFF?
High/Low Mode
Standard(2) and Memory(3) models only
When HiLo ON? is selected, the current Lo setting is
displayed. Adjust down
∅ or up ⊕. Alternatively, measure a
coating with a thickness close to the required value and
make final adjustments with the
∅ ⊕ buttons. Press ∅ ⊕
simultaneously to accept this value.
The last Hi setting is now displayed. Follow the same
procedure to adjust the Hi setting. The
symbol will
indicate H I L O M ODE is now ON.
Measurements will now be compared to your defined limits.
The Gage BEEPS TWICE (normal) if results are within
those limits and ONCE if outside. The single BEEP is a
LOW tone with a Ì if it is below the Lo limit, and a HIGH
tone with a Ê if it is above the Hi limit.
NOTE: the LED will only BLINK if readings are within limits.
S TATISTICS M ODE must be off. Calibration adjustments
cannot be made while in H I L O M ODE . To turn H I L O M ODE off
select "HiLoOFF?".
Memory Mode
Memory(3) models only
When MEM ON? is selected the symbol and a
counter ( 0) appear. 5000 readings in up to 100 batches
(groups) can be recorded.
In M EMORY M ODE readings are simultaneously displayed
and stored. The current BATCH number (B 1) is displayed.
Remove the last reading from memory by pressing
∅.
Erase ALL stored readings by selecting "CLR MEM?".
Calibration adjustments cannot be made while in M
EMORY
M ODE . To turn M EMORY M ODE off select "MEM OFF?".
NOTE: press ⊕ at any time to view the average, standard
deviation and number of readings in the current batch.
Batch Markers
Readings taken for different jobs or parts can be grouped
together or "separated" by placing Batch Markers between
sets of measurements. Select “B MARK?”. A Batch Marker
is set automatically if you turn H
I L O or S TATISTICS M ODES on
or off. Statistical summaries are calculated for each batch
during downloading.
Memory AND Statistics Modes Together
When both these MODES are ON, individual
measurements ARE NOT STORED. Instead, when
⊕ is
pressed, the average, standard deviation and number of
readings are simultaneously displayed and stored in
memory. Again, statistical summaries are calculated for
each batch during printing. This delivers the average of a
