Sifam Tinsley BETA 90A Operating Manual
The are digital panel meters for connection of measurement for voltage (10 V) and current
(1 mA, 20 mA or 4 ... 20 mA) with 4 ranges.
Operation:
The setting of measuring range and display range is made by positioning DIP switches. The chosen input range is
user adjustable from 10% to 100 % of the full scale value by potentiometer on the rear of the meter.
