LESSON 4
OPERATE SENSITOMETER, DENSITOMETER, AND
PLOTTING CONTROL CHART
OBJECTIVE:
In this lesson you will be told how to operate the Macbeth TD102 Densitometer, the Kodak
Model 101 Sensitometer, and how to transfer the readings onto a plotting control chart.
At the completion of this lesson you will be able to:
1.
Describe the function of an Eastman Kodak sensitometer and produce a sensistrip.
2.
Describe the function of the Macbeth TD-102 densitometer; read, record, and plot the

HOW TO PRODUCE A SENSISTRIP.
Prepare the sensitometer for use.
(1) Insure that the sensitometer is plugged into a 110-volt, 60-cycle outlet.
(2) Turn the sensitometer ON by rotating the lamp control knob (1) clockwise until it clicks ON.
(3) Record the time you turned the sensitometer ON in the sensitometer log.
NOTE:
THE TIME THE SENSITOMETER LAMP IS ON IS RECORDED, TO SHOW
WHEN THE 100 TO 150-HOUR LIFE OF THE LAMP HAS EXPIRED.
