Model 5030 SHARP Monitor Instruction Manual
The Model 5030 SHARP has a fixed flow rate of 1000 L/h (16.67 L/min).
The temperature control system that is used on the Model 5030 SHARP
Monitor is the Dynamic Heating System (DHS). A relative humidity sensor
is placed downstream of the optical sensing volume and upstream of the
beta attenuation sample chamber. The RH-sensor placement offers the
ability to measure the RH of the incoming aerosol. At this point in the
menu, only the DHS can be turned ON or OFF using the keypad. Press
NEXT.
Note T1 = ambient temp.,T2 = sample temp., T4 = Heater Wall Temp., and
HL = Heater Duty Cycle.
Additional DHS Settings are accessed using write-control commands. See
Appendix B.
The Model 5030 SHARP has one analog output channel (no. 1) on the
main board.
The analog output can be individually configured by jumpers: as voltage
output (0/2 -10V) or as current loop (0/4 - 20mA). The current output can
be equipped with a module for potential-free signal separation. For the
analog output a live zero signal (4mA or 2V) can be selected.
The assigned quantity for the analog output can be selected by the user. The
available quantities and their codes are listed in the table below. The symbol
is not shown in the configuration display. The user should assume the units
per quantity as listed in the following table.
