Martel Electronics T-150 [19C1977] Frequency Calibrator

A simple to use frequency calibrator for the process control industry
The T-150 precision frequency calibrator can generate or read the frequencies ranging from 1 count per minute to 100 kHz allowing it to be used for a wide range of flow measuring instrumentation. Operation of this calibrator is made easy through the use of a sealed membrane keypad with simple controls. The outputs are set through the use of step and ramp keys which allows both large and small output changes to be made with ease.

When operated in source mode, the user can quickly step the output in 10% of range increments or make smaller changes using the scroll keys.
