4.5.1 Measurement range setting
The DT-329 has a selectable measuring range, which can be set in the Parameter mode setting. The
range and resolution of this setting will be different for each measuring range, as indicated in the table
below.
Test unit Measuring range as Indicated in Parameter Settings
FPM
12,000
(range 60.0 - 12,000.0)
120,000
(range 60 - 120,000)
Hz
200
(range 1.000 - 200.00)
2,000
(range 1.00 - 2000.0)
*Note that if the flash range is changed to a lower range, the current flash rate, if larger than 12,000 FPM or
200 Hz, will decrease to the maximum allowable value of the range.
Ex: If flash rate is set to 60,000 FPM in the range of 60 – 120,000 FPM, it will automatically switch to
12,000 FPM when the flash measuring range parameter is changed to 60.0 – 12,000.0 FPM. The max
value is limited if the Flashing time (frequency) setting is greater than the range in the test range switch.
To adjust the measuring range parameter, press “PHASE +” or turn the dial clockwise to set the range as
“120,000 FPM” or “2000 Hz”
Press “PHASE -” or turn the dial counter clockwise to set the range as “12,000 FPM” or “200 Hz”.
