”
‘1’ Specify the Hi Q-RPT
‘2’ Specify the Lo Q-RPT
Arguments
“limit":
The upper limit pressure in the specified Q-RPT’s current pressure unit and
measurement mode.
Remarks The RPM4-E-DWT has an upper limit for each range and for each measurement mode (gauge,
absolute, and differential). If the pressure does exceed the upper limit, the pressure display
flashes. This feature should always be used to prevent accidental over pressure of a device
under test.
