Meter View:

The meter’s field of view is 50:1. For example, if the meter is 50 inches from the target (spot), the diameter of the target must be greater than 1 inch. Measurements should normally be made as close as possible to the 1” spot distance. The meter can measure from longer distances, but the measurement may be affected by external sources of light. In addition, the spot size may be so large that it encompasses surface areas not intended to be measured.

Emissivity:

D:S = 50:1          

Measurement Operations:

IR Temperature Measurements

  1. Hold the meter by its handle and point it toward the surface to be measured.
  2. Pull and hold the trigger to turn the meter on and begin testing. “SCAN” and the temperature reading will appear on the large display. The upper and lower sub-displays will indicate values/settings previously used.
  3. Release the Trigger and the reading will hold for approximately 7 seconds (“HOLD” will appear on the LCD) after which the meter will automatically shut off. The only exception to this is if the LOCK mode is set to ON.

The MODE button options

With the trigger pulled (SCAN displayed), Press the MODE button to view and scroll through:

MAX: Maximum value measured

MIN: Minimum value measured

DIF: Difference between the Max and Min values

AVG: Average of the measured values

LOG: A memory location is displayed in the small upper display and the value in that location is displayed in the small lower display. Press the ▲ or ▼ buttons to scroll through the locations.

With the trigger released (HOLD displayed), Press the MODE button to scroll through and access the following. The selected item is indicated by a blinking icon.

Recorded data: (Press the ▲ or ▼ button to scroll through and view)

ε =Emissivity (blinking ε=). Press the ▲ or ▼ button to set the value

Laser Pointer and Backlight Button

The laser pointers are designed to cross at a distance of 50” (76cm). The spot size at this distance is a 1” diameter and this is the recommended distance to target for most measurements. To turn the lasers on/off:

  1. Press and Hold the Trigger
  2. While SCAN is on the display, press and release the backlight/laser button ( ).

Either the backlight or laser pointers will change status (On/Off). Repeat this until the desired conditions are set. The laser icon will appear in the LCD when the laser function is enabled.

  1. The status of the functions will be stored in memory and will remain as the default “turn-on” condition until changed.

High and Low Alarm Feature

When either programmed alarm (high or low) point is reached the meter will alert the user via an audible beep and a blinking LCD display icon. The alarm limit is set and the feature is enabled/disabled using the MODE button. The setting is stored and memory and will remain as the “turn-on” condition until changed.

Temperature Units

The temperature units can be set to °F or °C. The selection is made using the MODE button.

Lock feature

The LOCK feature disables the Auto Power Off feature for the period of use when selected. The feature is useful for long term temperature monitoring and hands free use.

The meter will revert to auto power off if the trigger is pressed during a locked scan. The selection is made using the MODE button.

Over-range Indication

If the temperature measurement exceeds the specified temperature range, the thermometer will display dashes in place of a temperature reading.

Data Logger

Storing Data: The thermometer is capable of storing up to 100 data points.

Infrared: To store data from an infrared reading,

  1. Pull and Hold the trigger
  2. Press the MODE button until LOG appears in the lower left corner of the display; a log location number will be displayed. If no temperature has been recorded in the displayed LOG location, 4 dashes will appear in the lower right corner.
  3. Aim the unit at the target area you want to record, and press the laser/backlight button. The recorded temperature will appear in the lower right corner.
  4. To select another log location, press the up and down keys

Recalling Data: To recall stored data after the unit shuts off,

  1. Press the MODE button until LOG appears in the lower left corner and the stored temperature for that location will be display.
  2. To move to another LOG location, press the UP and Down keys.

Log Clear Function: To clear the memory,

The “Log clear” function allows you to quickly clear all logged data points. This function can only be used when the unit is in the LOG mode.

  1. While in LOG mode, press the trigger, and then press the “down” arrow button until

LOG location “0” is displayed. Note: This can only be done when the trigger is pulled. LOG location “0”cannot be accessed, by using the “up” arrow button.

  1. When LOG location “0” shows in the display, press and release the laser/backlight button, then press and release the up arrow key. A tone will sound, and the LOG location will automatically change to “1”, signifying that all data locations have been cleared

IR Measurement Notes

  1. The object under test should be larger than the spot (target) size calculated by the field of the diagram
  2. Before measuring, surfaces should be clean and covered with frost, oil, grime, etc.
  3. If an object’s surface is highly reflective, apply masking tape or flat black paint to the surface before measuring. Allow time for the paint or tape to adjust to the temperature of the surface it is covering.
  4. Measurements through transparent surfaces such as glass will not be accurate.
  5. Steam, dust, smoke, etc. can obscure measurements.
  6. The meter automatically compensates for deviations in ambient temperature. However, it can take up to 30 minutes for the meter to adjust to extremely wide changes.
  7. To find a hot spot, aim the meter outside the area of interest then scan across (in an up and down or side to side motion) until the hot spot is located.
