4.8 SELECTING THE MEASUREMENT RATE & RESOLUTION
Three user selectable measurement repetition rates are available;
4, 8 and 16 Hz - the gauge will take 4, 8 or 16 readings per second
depending on the rate selected.
To select the reading rate, press Menu/Setup/Reading/Reading Rate.
When in 'Scan Mode' - see Section 10.3 'Taking a Reading in Scan
Mode' on page en-22 - the reading rate is set at 16 Hz
(16 readings per second).
The gauges have a user selectable reading resolution of 0.1mm
(0.01") - 'Low', or 0.01mm (0.001") - 'High', which gives more precise
readings when measuring on thinner materials.
To select the resolution, press Menu/Setup/Reading/Resolution and
select 'Low' or 'High' as required.
5 SETTING LIMITS - MTG8
Limits are acceptable tolerance levels as defined by the user allowing
the user to compare readings to pre-defined values. The MTG8 can
store up to 40 pre-programmed limits.
Limits can be created on the gauge or via PC using ElcoMaster , and
saved into the gauge memory for future selection. Using ElcoMaster ,
saved limits can be transferred to other MTG8 gauges.
Each Limit can consist of a nominal or target value (x:) - required for
'Readings & Differential' - a low (
Limits can either be created for individual readings or when a new
batch is opened, see Sections 5.1 and 5.2. Different batches can have
different limit values.
