I. INTRODUCTION
This IR Probe is heavy duty and compact and the microprocessor circuit
assures a high degree of accuracy. Measures °C and °F, with a preset
emissivity value of 0.95, that accommodates most applications. With the
plug-and-play feature of this probe, calibration procedures are not required. The meter features Hold, Max./Min, RS232 and Auto Shut Off.

III. MEASUREMENT PROCEDURES
•
Plug probe into the PROBE INPUT SOCKET.
•
Make sure the PROBE LOCK is in the lock position
•
Turn on the instrument by pressing the POWER button.
•
Point the probe toward the source to be measured. The distance-tospot (D/S) ratio is approximately 7 to 1. Press the
°C/°F (A)
button to
select Centigrade or Fahrenheit. The temperature is displayed on the
LCD.
Refer to the Environmental Quality Meter 850071 Instruction Manual for
complete instructions about Hold, Max./Min, RS232, Auto Shut Off, and
other functions.
Temperature Adjustment
Environmental conditions such as low temperatures and rapid temperature
changes may cause the reading to drift by 1 to 3 degrees. If a deviation
occurs, slightly turn the temperature adjustment until a correct reading is
obtained.
Field Distance/Spot (D/S)
The distance-to-spot factor is approximately 7-to-1. The object must be
larger than the spot size as calculated by the Distance/Spot ratio. For an
accurate measurement, a 1.5 times distance/spot size is recommended.
Emissivity
The probe has an emissivity value of 0.95, which will cover 90% of the
typical applications. If the emissivity value of the object is not 0.95 or if it's
surface is highly reflective, apply masking tape or a paint with a 0.95 emis-
sivity value. Clean the surface if it is covered with frost or other matter
.
