8.2 Button functions
The buttons may change functions in different menus. Always read the text, just
above the buttons in the display, for the button functions.
All changes in values are valid only when saved using the Save or Enter button
(button 4). All changes is saved into the instrument. Only Trigg Level is stored into
the probe.
Use the Undo or Esc button (button 1) to delete a change in value and revert to the
previous setting.
Use the Esc button (button 1) to browse backwards through the menus to the start
position Locating Mode/Measuring Mode .
To change quickly from Locating Mode to Measuring Mode or vice versa, press button 4
three times in succession.
8.3 Stored values and setups
All values and instrument setups is saved into the instruments memory. Only the Trig
Level is stored into the hand probes memory. That mean that you easily can change
the probe to another one and still keep your setup.
8.4 Engineering format
Some of the parameters of the detector are written in engineering format. This
format can represent a very wide range of numbers from very small to very large
numbers.
The following examples describes the format used in the detector:
1.00E+01 = 1.00 x 10
1
= 10
1.00E+00 = 1.00 x 10
0
= 1
1.25E-02 = 1.25 x 10
-2
= 0.0125
8.5 Change Test Mode
Choose the test method you will use in the menu Change Test Mode. There are
three different methods to choose:
• Measuring Mode
• Locating Mode
• Combined Mode*
* Not in ILS500 Mode
See Reference section for a description of the functions.
8.6 Calibration
Calibrate
The instrument must be calibrated by using the integral calibration function to
ensure it displays the correct values in
Measuring Mode/Combined Mode . After
calibration the instrument will show the correct measured values on the display.
If the probe is replaced with another probe a new calibration must be performed.
