2. Design and function
2.2 Description
The hand test pumps CPP700-H and CPP1000-H serve as pressure generators for the
testing, adjustment and calibration of mechanical and electronic pressure measuring
instruments through comparative measurements. These pressure tests can take place in
EN
the laboratory or workshop, or on site at the measuring point.
By connecting the pressure measuring instrument to be tested and a sufficiently accurate
reference measuring instrument to the CPP700-H or CPP1000-H, on actuating the pump,
the same pressure will act on both measuring instruments. By comparison of the two
measured values at any given pressure value, a check of the accuracy and/or adjustment
of the pressure measuring instrument under test can be carried out.
The hand test pumps, despite their very compact dimensions, enable simple and
accurate pressure generation. The CPP700-H and CPP1000-H have a fine adjustment
valve for precise adjustment, so as to ensure an accurate comparison test. The reference
instrument is screwed directly to the top of the pump, and the test item is connected using
the connecting hose included in delivery.
