Badger Meter Portable Hydraulic Testers - Manual (Page 8)

To prolong battery life on all testers, turn off the tester when the tester is not being used . Either return the toggle switch to
the OFF position on the PFM6 and PFM6BD models, or press OFF on the PFM8 model .
Once the tester has been installed, the pressure can be regulated by operation of the loading valve .
MPORTANT I
Always start with the loading valve open.
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.
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).
The PFM6 and PFM8 testers are equipped with a poppet style loading valve . The PFM6BD testers use a spool design loading
valve to accommodate bi-directional flow . The spool design requires more turns to go from total open to total close .

Pressure is displayed as follows:
PFM6 The gauge indicates pressure at the inlet port
PFM6BD The gauge indicates pressure at the inlet port dependent on the direction of flow
PFM8
The pressure is displayed on the LCD . A minimum of 200 psi (14 kg/cm 2 ) is required to activate the display . The
psi will increment in 10s (for example 200, 210, 220); kg/cm 2 , bars or MPA will increment in single units (for
example 141, 142, 143, etc .)
On all models, the battery voltage is affected by cold temperatures . Allow time for the circulating oil to warm the tester before
critical measurements are taken . On the PFM6 and PFM6BD, a LO BAT signal on the display indicates a low battery condition .
On the PFM8, a flashing colon on the display indicates a low battery condition . Replace the batteries with four AA alkaline
batteries . See "Battery Replacement" on page 15 .
