1.1 Introduction
The OS530/OS520 series Handheld Infrared (IR) Thermometers provide non-contact temperature measurements up to 4500°F. They offer effective solutions for many non-contact temperature applications, including the following:
•Predictive Maintenance: Tracking temperature shifts which indicate pending failure in solenoid valves.
•Energy Auditing: Locating wall insulation voids to reduce building heating costs.
•Food Processing: Taking accurate temperature readings without direct contact with the food or packaging material.
The IR thermometer provides information at a glance — the custom backlit dual digital LCD displays both current and minimum, maximum, average or differential temperatures. This versatile instrument provides:
•Measurable target distances from 5 inches to approximately 100 feet
•Emissivity adjustable from 0.1 to 1.00 in 0.01 steps provides ease of use when measuring a variety of surfaces.
•Built-in Laser sighting in Circle & Dot configurations.
•Thermocouple input available.
•An electronic trigger lock feature set via the keypad allows continuous temperature measurement up to 4 times per second.
•Audible and visual alarms. The high and low alarm points are set via the keypad.
•1 mV per degree (°F or °C) analog output, which allows interfacing with data acquisition equipment (including chart recorders, dataloggers and computers). OS524 provides 0.5 mV/Deg.
•Last temperature recall.
•Backlit display useful in low ambient light conditions.
•Powers from 4 AA size batteries or an ac adapter.
•RS232 serial communication to a PC or printer. This allows downloading data for further analysis.
•Ambient target temperature compensation. This provides more accuracy for measuring low emissivity targets.
•Record up to 100 temperature data points. Review the recorded data on the thermometer LCD, as well as downloading the data to a PC.
1-1
1 General Description
The thermometer is easy to use:
•Units have standard “V” groove aiming sights.
•Integral tripod mount permits hands-free operation, if necessary.
•Temperature readings are switchable from °F to °C via the keypad.
•Parameters, such as target material emissivity and alarm setpoints, can be set and remain in memory until reset.
This instrument has a rugged and functional design, including:
•Sealed keypad display.
•Convenient trigger operation.
•Soft carrying case and wrist strap, for safety and ease of carrying.
•Rubber boot around the lens and the display.

2.1 How to Power the Thermometer
2.1.1 Battery Operation
Invert the thermometer and install 4 fresh AA size batteries as shown in Figure 2-1. Make sure the batteries’ polarities are correct, the batteries are not put in backwards, and are of the same type.
NOTE
If the icon flashes, the batteries must be replaced with fresh batteries immediately.
Figure 2-1. Installing the Batteries
2.1.2 ac Power Operation
The thermometer may be operated on ac power using the optional ac adapter. 120Vac/60 Hz and 220Vac/50 Hz adapters are available. When operating on ac power the batteries supply backup power in case of ac power failure. The ac adapter input jack is shown in Figure 1-3.
2-1
2 Using the Handheld Infrared Thermometer
2.2 Operating the Thermometer
1a. (Without the Laser Sighting) -Aim the thermometer at the target to be measured. Use the “V” groove (shown in
Figure 1-1) on top of the thermometer to align the target to the thermometer’s field of view. Look down the “V” groove with one eye only, in order to guarantee proper sighting.
Pull and hold the trigger.
1b. (With the Laser Sighting) - Set the laser power switch to the ON position. Aim at the target and pull the trigger. The laser beam and the red power indicator LED will turn on while the trigger is pulled. Refer to Chapter 3 for more details on the Laser Sighting.
Figure 2-2. OS530/OS520 Series with Built-in Laser Sighting
2.The field of view of the thermometer should fall within the area
of the target being measured. See Figure 2-3. Figures 2-4 through 2-6 show the field of view vs distance for the various thermometers.

3.The target temperature and emissivity are displayed on the LCD. Determine the emissivity of the target (refer to Appendix B). Press the
key to increment the target emissivity. Press the key to decrement the target emissivity.
4.Press the key to lock the trigger. The icon will appear on the display. This allows the thermometer to operate continuously
whether or not the trigger is pulled. To unlock the trigger, press the
key again. The icon is no longer displayed. When the trigger is pulled, the Laser Sighting as well as the display backlight
will stay on .
5.After completing a temperature measurement, release the trigger. In order to conserve battery life, the thermometer goes into sleep mode and the Laser Sighting turns off.

2.2.1 Measurement Techniques
You can use the IR Thermometer to collect temperature data in any one of five different ways:
•Spot Measurement — Measures the temperature of discrete objects such as motor bearings, engine exhaust manifolds, etc.:
1.Aim at the desired target and pull the trigger.
2. If necessary, adjust the emissivity using the |
and |
keys. |
|
3.Read the temperature.
•Differential Measurement — Measures the temperature differential between two spots (the maximum and minimum temperatures viewed)
1.Aim the thermometer at the first spot and pull the trigger. Press the key to lock the trigger.
2.If necessary, adjust the emissivity.
3.Aim at the second spot.
4.Adjust the emissivity of the second spot if required.
5. To display the differential temperature, press the |
key until |
“dIF” appears on the display. |
|
6.Read the differential temperature from the upper display.
7.Press the key to unlock the trigger.
•Static Surface Scan – Measures the temperature across a static
surface:
1.Aim the thermometer at a starting point and pull the trigger. Press the key to lock the trigger.
2.If necessary, adjust the emissivity.
3.Slowly move the thermometer so that the line of sight sweeps across the surface. The thermometer measures the temperature at each point on the surface.
4.To record the temperature profile across the surface, connect the IR thermometer to a strip chart recorder. Refer to Figure 2-7 for details. The IR thermometer provides an analog output of 1mV/degree. (0.5 mV/Deg on OS524)
5. After all the data has been taken, press the |
key to unlock |
the trigger. |

•Moving Surface Scan - Measures the Temperature of Points on a Moving Surface:
1.Mount the thermometer on a camera tripod and aim at a fixed point on the moving surface.
2.Pull the trigger and press the key to lock the trigger.
3.If necessary, adjust the emissivity. The thermometer is now set up for measuring the temperature of a moving surface.
4.To record the temperature profile of the moving surface, connect the IR thermometer to a strip chart recorder. Refer to Figure 2-11 for details.
5.After all data is taken, press the key to unlock the trigger.
•Fixed Point Monitoring Over Time - Monitors the temperature at a fixed point over time:
NOTE
It is recommended that you use the ac adapter for long term measurement of temperature.
1.Mount the thermometer on a camera tripod and aim at the target.
2.Connect the analog output of the thermometer to a strip chart recorder as shown in Figure 2-11.
3.Pull the trigger and press the key to lock the trigger.
4.If necessary, adjust the emissivity.
5.The thermometer is now set up for unattended monitoring of temperature over time. You can also download the temperature to a Serial Printer or a PC for further analysis (Models OS533, OS534, OS523, OS524).
6.After all data is taken, press the key to unlock the trigger.

2.3 Real Time Mode (Active Operation)
Definition: Real Time Mode is the active operational mode of the thermometer. In this mode, the thermometer constantly measures and displays temperature.
Figure 2-12. General Operational Block Diagram
NOTE
If the trigger is pulled two times in rapid sequence,
it may reset the emissivity, high alarm, low alarm and target ambient temperature to the default values.
