INTRODUCTION:
MTR-600 IS A MICROCONTROLLER BASED INTELLIGENT CIRCULAR CHART RECODER. THE
UNIT FEATURES TWO ANALOG INPUTS, SIXTEEN CHARACTER BY ONE LINE BACKLIGHTED LCD
DISPLAY. MTR-600 UNIT HAS STEPPER MOTOR FOR THE CHART AND PEN MOVEMENT. MTR-600
UNIT HAS NONVOLATILE MEMORY FOR STORAGE OF PARAMETERS AND STORAGE OF
CALIBRATION DATA, BATTERY BACKED CLOCK TO COMPUTE THE POWER OFF TIME, SELECTION
OF INPUT TYPE, PROGRAMMABLE CHART DURATION AND PROGRAMMABLE LOW AND HIGH POINT
IN ENGINEERING UNITS FOR THE PEN LIMITS ON THE CHART.
THE RECORDER ON POWER ON MOVES THE PEN TO ZERO POSITION. IT THEN MOVES THE
CHART AHEAD WITH RESPECT TO THE TIME ELAPSED DURING POWER OFF. IT THEN MOVES BOTH
THE PENS TO THE RESPECTIVE POSITION ON THE CHART AS PER THE ANALOG INPUT.
THE RECORDER READS ON THE DISPLAY THE VALUE OF THE TWO ANALOG INPUTS IN
ENGINEERING UNITS AS CALIBRTATED. THE ANALOG INPUTS CAN BE SET EITHER FOR A LINEAR
INPUT, OR RTD, OR THERMOCOUPLE (J,K,R,S,T). THE RECORDER IS LINEARISED FOR THE RTD, J, K,
R, S AND T INPUTS. THE RECORDER CAN BE CALIBRATED BY KEYS ON THE FRONT. FOR A LINEAR
INPUT THE RECORDER CAN BE CALIBRATED TO A RANGE OF –0999 TO +8999 UNITS, WITH
PROGRAMMABLE DECIMAL POINT POSITION.
THE RECORDER CAN BE PROGRAMMED FOR THE LOW AND HIGH RANGE OF THE PEN LIMIT
AS PER THE CHART. THE LOW RANGE AND THE HIGH RANGE CAN BE PROGRAMMED FROM –999 TO
+8999 UNITS. THE RECORDER CAN BE SET FOR THE CHART DURATION OF 8 HOURS, OR 24 HOURS
OR 7 DAYS. ALL THE PROGRAMMED PARAMETERS ARE STORED IN A NONVOLATILE MEMORY AND
REMAIN INTACT EVEN IN POWER OFF CONDITION.

SIXTEEN CHARACTER BY ONE LINE BACKLIGHTED LCD DISPLAY.
POWER UP STATUS:
THE CIRCULAR CHART RECORDER WHEN CONNECTED TO MAINS SUPPLY – THE DISPLAY
OF THE RECORDER FOR TWO SECONDS READS
“ DPM INSTRUMENTS ”
AFTER TWO SECONDS THE DISPLAY READS “MOVE P1 TO ZERO”. DURING THIS TIME THE PEN # 1
IS BEING MOVED TO ZERO POSITION.
AFTER THE PEN # 1 HAS REACHED TO ZERO POSITION, THE DISPLAY READS “MOVE P2 TO ZERO”.
DURING THIS TIME THE PEN # 2 IS BEING MOVED TO ZERO POSITION.
AFTER THE PEN # 2 HAS REACHED TO ZERO POSITION, THE DISPLAY READS “MOVE CHART ”.
DURING THIS TIME THE CIRCULAR CHART IS BEING MOVED FORWARD, WITH RESPECT TO THE
TIME ELAPSED DURING POWER OFF. THIS IS TO ENSURE THAT THE CHART MOVES ONE
COMPLETE ROTATION IN THE DESIRED AMOUNT OF TIME.
THEN THE DISPLAY READS THE ACTUAL PROCESS VALUE FOR INPUT # 1 AND INPUT # 2.
THIS IS THE MAIN MENU OF THE RECORDER UNIT. THE RECORDER UNIT CAN BE PROGRAMMED
FOR THE LOWER AND UPPER RANGE OF THE PEN LIMITS IN ENGINEERING UNIT. THE INPUT TYPE
CAN BE SET EITHER LINEAR, OR RTD PT100 OR J, K, R, S T THERMOCOUPLE. FOR LINEAR INPUT
THE DECIMAL POINT POSITION IS PROGRAMMABLE AS PER THE USER REQUIREMENT. THE
CALIBRATION OF THE INPUT CAN BE DONE BY KEYS. IF THE INPUT TYPE IS CHANGED THEN THE
CALIBRATION IS TO BE PERFORMED AGAIN.
