The PHM-100 is a portable
hand-held digital indicator
for strain gage bridge type transducers such as load
cells,
torque sensors and pressure sensors. It
provides bridge excitation, balance, span
adjustment, shunt calibration,
decimal point selection and digital display. When peak hold
is in the on position, the highest static or dynamic
signal is captured at less than one millisecond and displayed
until reset. The PHM-100 operates on a standard
9 volt battery for 60 hours and is equipped with a low battery
Indicator.
