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' (PTG8 only) - see Section 9.3 'Taking a Reading
in Scan Mode' on page en-20 - 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 - PTG8

Limits are acceptable tolerance levels as defined by the user
allowing the user to compare readings to pre-defined values. The
PTG8 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 PTG8 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.
When created, limits are stored in the gauge limit memory and are
available for future selection, see Section 5.3.
Saved limits can be renamed and the values can be amended at
any time, see Sections 5.4 and 5.5.
