Counter Timer (AT) [ TYPE : CT 541A ]
Counter Timer (AT) CT 541A manufactured by NUCLEONIX is an advanced technology based unit designed around a eight bit microcontroller chip. This unit is very versatile and can be operated in three modes namely PRESET TIME, CPS & CPM modes.
The user interface is through built-in keypad command buttons START, STOP, PROG, STORE/RECALL, INC & DEC. The visual indication is through LCD dotmatrix display. It has on board memory to store 1000 readings. The stored data readings can be recalled onto display or can be printed on a printer.
This unit has a built-in parallel port (centronics) facilitating direct data printing and a serial port RS 232 for connecting to a PC, for data communication.
The other features include programmability for assigning lables for the readings such as BG – for background, ST – for standard and SP – for sample counting.
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 time, elapsed time and counts.
