DOUBLE
Calibration Steps:
3. The temperature offset is displayed. The offset is the difference
between the RTD temperature reading and the thermometer's
temperature reading. Select SAVE to use the new temperature offset or
manually enter an offset correction factor.
1. In the EDIT mode set the temperature on the instrument to the rated
temperature of your thermometer and wait for it to lock in. Enter the
SYS, CALIB mode and select RTD Sensor DOUBLE. Insert the first
thermometer into the thermometer well. Let the RTD and the first
thermometer stabilize in the barrel for 15 minutes. Once the
temperature has stabilized, press STABLE to proceed.
2. Enter the first thermometers temperature accurate to 1/10 degree
Celsius.
3. Set the temperature on the instrument to the rated temperature of the
second thermometer and wait for it to lock in. Insert the second
thermometer into the thermometer well. Let the RTD and the second
thermometer stabilized in the barrel for 15 minutes. Once the
temperature has stabilized, press STABLE to proceed.
4. Enter the second thermometers temperature accurate to 1/10 degree.
5. The temperature offset is displayed along with gain. The offset is the
difference between the stabilized temperature reading and the
thermometer's temperature readings. Select SAVE to use the new
temperature offset and gain values or manually enter an offset
correction factor and gain value.
Optical Flag
The instrument allows for the adjustment of the Optical Flag sensitivity. The
sensitivity determines how sensitive the Optical Flag LED Receiver is to being
in either two states, blocked or open. Sensitivity directly affects the measured
length of the tape flag.
The Optical sensor is calibrated at Dynisco Polymer Test prior to shipment.
There should be no need to re calibrate the RTD sensor. For this procedure you
must have the Flag Calibration Unit.
1. Select Optical Flag in the Calibrate Select mode.
2. Make sure FLAG STATUS = OPEN when there is no flag blocking
Optical Sensor. Typical sensitivity readings are 50.
3. Place the electronic eye calibrator on top of the instrument and hang
a tape with a ¼" flag on its pin. The tape should hang such that it
extends down through the slot on the top right hand side of the
instrument.
3. Adjust the calibrator to lower the flag down until it just blocks the
optical sensor and the instrument display reads FLAG STATUS =
CLOSED. Set the calibrator dial to zero. Continue to lower the flag
until the flag leaves the sight line of the eye and the instrument display
reads FLAG STATUS = OPEN. Note the dial travel of the tape, it
should be within +/- 0.002 inches of 0.250 inches.
