Figure 2: PFM6 and PFM6BD Toggle Switch
Flow is identified by the symbol and the symbol indicates temperature Horsepower readings will be followed by the symbol
and kilowatt by a symbol
NOTE:
If no flow has been present for five minutes, the power saver circuit will automatically shut the PFM8 off Pressing the
“ON” switch will restore power
To prolong battery life on all testers, select the “OFF” option by returning the toggle switch to the “OFF” position on the PFM6
and PFM6BD models or pressing “OFF” on the membrane switch of the PFM8 model when the tester is not being used
Once the tester has been installed, the pressure can be regulated by operation of the loading valve
ALWAYS START WITH THE LOADING VALVE OPEN
WARNING
Warning - Turn the loading valve handle counterclockwise to open before starting machinery. Injury to personnel
and/or damage to the equipment can result if the loading valve is fully closed.
CAUTION
Caution - The PFM6BD is not designed for high pressure “deadhead” (loading valve fully closed) applications, in the
reverse direction. Usage under this condition could lead to loading valve failure. Under such conditions, maximum
operating pressure is limited to 2000 PSI (138 Bar).
