Terwin DG7 Series
The Terwin DG7 Series is a battery powered micro‐processor controlled, high accuracy and versatile digital
pressure measuring instrument with integrated fast peak, maximum and minimum functions.
The instrument can be used in one of two modes:
The pressure is measured twice per second and displayed. The top display indicates the actual pressure. The
bottom display shows the maximum or minimum pressure since the last reset.
The pressure is measured 5,000 times per second and is brought to the display twice per second. The top
display shows the actual pressure. The bottom display shows the peak (maximum) or trough pressure
The Terwin DG7 Series has two operating keys. The left key is to turn the instrument on, to select the functions and the pressure units. The right
key executes the selected function or unit. The right key is also used to switch between the MAX. and MIN. values in both modes.
