Dual Scaler Timer Type CT542A manufactured by NUCLEONIX is designed around a microcontroller chip and has 12 x 2 LCD dotmatrix display.
This unit can be used in three modes PRESET TIME, CPS & CPM modes. It has on board memory to acquire readings upto 1000. The stored data readings can be recalled onto display or can be printed onto a printer. It can count two inputs simultaneously.
This unit has a built-in parallel port (centronics) and a serial port RS 232 for connecting to a PC.
It is built as a two bit module. It can count both positive and negative pulses in the range of 100 mV to 10V and upto a maximum frequency of 1MHz. LCD display indicates preset and elapsed time and counts of any selected channel.
Programmability of ONE, TWO & FOUR iterations for any particular counting. |
