6. CALIBRATION
Perform Single Point Calibration (Set Flow) Figs 27, 28, 29 and 30. This allows the user to
set the required flow rate for the sample to be taken and check with an external flow
calibration device.
Note: “Flow Set” and “Reset” options are not available in Partial Lock mode.
From Main Menu , press UP/DOWN keys to go to SET FLOW. Press ENTER to access Set
Flow options. Use UP/DOWN keys to adjust the flow setting required. Press ENTER to
continue.
PRO and PLUS ONLY
- Use UP/DOWN keys to calibrate the Sampler flow setting
.
Figure 27 Set Up Calibration
WARNING:
Only set CAL FLOW when connected to an external calibration device to
prevent false flow rates being set.
Attach a sampling head and flow tube or other flow-measuring device to the pump’s inlet
nozzle to measure the actual flow as shown in Figures 28, 29 and 30. Press the UP/ DOWN
keys to adjust the flow rate until the value shown on the flow measuring device agrees with
the required flow rate.
(Note Tuff standard models do not show the flow rate on the pump display. Use UP/DOWN
keys to alter flow shown on calibration device until the required flow rate is reached.)
Press ENTER to set the flow rate and return to the Main Menu.
