Overview INTRODUCTION     The T-900 Series calibration hand pump, designed by Mansfield & Green, generates pressure for verifying, adjusting and calibrating mechanical and electronic pressure measurement devices. This hand pump is suitable for pressure tests in laboratory and field settings. The T-900 Series calibration hand pump is easy to operate and allows for precise pressure generation. Combination models include a shuttle valve to allow vacuum generation as well. CPF versions include Crystal Pressure Fittings (CPF), which allow users to produce leak-free seals without tools or thread tape....

FEATURES AND PARTS LISTS     Each hand pump includes a fine adjustment knob for precise pressure adjustments. The reference instrument threads directly to the top of the pump (if using a supplied quick connector). The device-under-test connects to the pressure hose via the supplied adapters.

Operating and Safety Instructions   5 Operating and Safety Instructions CONNECTIONS     Reference Pressure Port Connections The reference indicator threads to the upper side of the calibration hand pump. A finger-tight connection is sufficient (if utilizing an AMETEK Jofra quick connector or a CPF fitting). If adapters are used, bonded seals and Teflon tape may be necessary. AMETEK Jofra fitting connection. Crystal CPF fitting connection. Device-Under-Test Pressure Port Connections In order to adapt the different connection threads of the device-under-test, the pressure hose can be fitted with...

Operating and Safety Instructions   6 GENERATING PRESSURE AND VACUUM     XX Actuate the Shuttle Valve (Combination Models Only) Verify that the shuttle valve is positioned to provide pressure or vacuum. Use a pen or a small screwdriver for this purpose. The encasement of the switch is intended to help prevent unintentional actuation. (Only applies to models T-965, T-975, and T-975-CPF.) Shuttle Valve !!CAUTION: Never actuate the shuttle valve while the hand pump is under pressure or vacuum. Actuate the shuttle valve only when the pump is vented. XX Apply Pressure or Vacuum 1 Verify that the vent...

Operating and Safety Instructions   7 3 Zero your reference indicator. 4 Close the vent valve. To apply pressure... 5 Operate the hand pump until the target pressure is nearly reached, but no more than 25 bar (for T-970, T-975, and T-975-CPF) or 1.5 bar (for T-960 and T-965). 6 Turn the fine adjustment valve to reach the target pressure, as indicated on the reference indicator. Note: After increasing pressure, the reading may drop slightly. This is due to thermodynamic or adiabatic effects , hose expansion, and sealing gaskets. If pressure does not stabilize, check the measuring circuit for tightness....
