Display Size
When in Measurement mode a large number display can be activated for easier reading. This simply
gives the reading in milliseconds without the additional data. However, all the normal statistics and
readings are still stored, it’s just an alternate display mode should it be required.
Display Average
In Measurement mode, whilst readings are being stored for future analysis a running average of the
current measurement session can be displayed. There is a choice between the average being displayed
in milliseconds ( M/Sec ) or frames ( Frames ). If frames are chosen but no frame rate is set,
the display will show the average in milliseconds. This is handy to see if this running average is starting
to head up or down, which can indicate a small delay error getting worse over time. The average can
be calculated over huge numbers of consecutive readings, although any ‘false’ readings will be included
within the average. Millisecond and frame averages are indicated by an A or A
F
respectively.
Frame Rate
A video frame rate per second can be entered using the keys, which is used to calculate
the millisecond delay measured into frames. Any frame rate from 1 to 120 can be entered.
Holding an arrow key will step up/down in 10’s and pressing the key will quickly reset the value
to zero.
In the screen below, a frame rate of 30 Frames/Sec has been input.
User ms Offset
A manual offset can be input, when an offset is set the readings are tagged with a symbol to
indicate the setting is active. The offset entered is processed during readings and statistics calculations.
Holding an arrow key will step up/down in 10’s and pressing the key will quickly reset the value
to zero.
In the screen below, an offset of 45 milliseconds has been input, with a frame rate of 25 frames/sec
having previously already been set.
