9.5 Flow readout adjustment
The sensor module in the M300 consists of a flow
sensor and a pressure sensor. See Figure 9.2 for a
diagram of this module. From these three sensors
two values are displayed on the front panel TEST
function area. These are:
•
Sample flow
•
Sample cell pressure
In order to adjust the flow or pressure read
out, select the desired test function on the
front panel and adjust the appropriate pot
for the desired value per Figure 9.2.

9.6 DC power supply
Overall performance of the DC power supply may be checked by observing the value
displayed during test DCPS. If this value, a composite of the five (5) regulator outputs,
deviates by more than 10% from the value recorded in Table 1.1 of this manual under
Test Values, the outputs of the individual regulators should be measured.
Test points 1, 2, 3 and 4 provide connection to the temperature outputs on drawing no.

9.7 CPU
If the display is operating and the green sample light is on, the CPU should be operating.
If not, check for +5v to the CPU.
