Using the chek-mate Flowmeter
value or no airflow (‘- - - -’ indicated on the screen) the flowmeter will automatically switch
off after 15 minutes to preserve battery power.
3) CalChek Flow Calibration
a. To perform automatic flow calibration of SKC AirChek 2000, AirChek 3000 and AirChek
Touch pumps using the 375-0550 chek-mate, the optional CalChek communication
cable (P/N 375-200) is required. Plug one end of the cable into the socket on the right
hand side of the chek-mate flowmeter and the other end of the cable into the serial
interface socket on the pump (the socket is mounted on the charging cradle for the
AirChek Touch pump and the pump must be fitted to the charging cradle to perform
CalChek calibration).
b. When performing a single point CalChek calibration of a complete sample train connect
the outlet port of the chek-mate to the inlet of the sample train (using a calibration
adapter if required).
c. A full CalChek calibration, which automatically calibrates the pump across its entire
operating range, is performed with no sample train connected between the chek-mate
and the pump. A pulsation dampener (P/N 375-100) is therefore required to be connected
in place of the sample train between the chek-mate outlet port and the pump inlet port.
d. The CalChek function is initiated on the pump. Refer to the specific pump users manual
for detailed instructions on this. When airflow through the chek-mate is detected the
