Manual

1 Introduction

Thank you for purchasing an infrared thermometer PCE-889B from PCE Instruments.

2 Safety notes

Please read this manual carefully and completely before you use the device for the first time. The device

may only be used by qualified personnel and repaired by PCE Instruments personnel. There is no

warranty of damage or injuries caused by non-observance of the manual.

- The device may only be used in the approved temperature range.

- The case should only be opened by qualified personnel of PCE Instruments.

- Only use PCE replacement parts or appropriate equivalent.

- The instrument should never be placed with the user interface facing an object (e.g. keyboard side on a

table).

- You must not make any technical changes to the device.

- The appliance should periodically be cleaned with a dry cloth / use only pH-neutral cleaner, no

abrasives or solvents.

- Be extremely careful when the laser beam is turned on.

- Do not let the beam enter your eye, another person’s eye or the eye of an animal.

- Be careful not to let the beam strike your eye via a reflective surface.

- Keep the instrument away from explosive gases.

- It is not recommended to measure shiny or polished metal surfaces (stainless steel, aluminum, etc.) with

this thermometer, see information on emissivity.

-The device cannot measure through transparent surfaces such as glass. It will measure the surface

temperature of the glass instead.

- Steam, dust, smoke, etc., can obstruct the meter’s optics and thus affect measurement accuracy.

This user's handbook is published by PCE Instruments without any guarantee.

We expressly point to our general guarantee terms which can be found in our general terms of business.

If you have any questions please contact PCE Instruments.

5 Background information

Distance to spot size ratio

As you can see below, the spot size (S) of the area measured by the unit becomes larger as the distance

(D) from the object increases. In both cases illustrated below, the focal point is 914 mm (36”). The spot

sizes indicate 90 % encircled energy.

Field of view

Make sure that the target is larger than the spot size. The smaller the target, the closer you should be to

it. When accuracy is critical, make sure the target is at least twice as large as the spot size.

Emissivity

Emissivity is a term used to describe the energy-emitting characteristics of materials. Most (90 % of

typical applications) organic materials and painted or oxidized surfaces have an emissivity of 0.95 (pre-

set in the device). Inaccurate readings will result from measuring shiny or polished metal surfaces. To

compensate, cover the surface to be measured with masking tape or a thin layer of black paint. Allow

time for the tape to reach the same temperature as the material underneath it. Measure the temperature

of the tape or painted surface.

6 Button functions / Instructions

°C / °F switch

Using this switch, you can select °C or °F as your unit of measurement. You can find the switch behind

the battery compartment cover, above the batteries.

Settings and selection within the different modes using the up / down buttons

During measurement, the up and down buttons can be used to adjust the emissivity.

When in HOLD mode, the up key can be used to turn the laser on or off and the down key is used to turn

the backlight on or off.

MODE button

By means of the MODE button, you can navigate through the mode cycle where you can make several

settings. To set, for example, the values for the High Alarm (HAL), Low Alarm (LAL) and Emissivity

(EMS), press the MODE button until the appropriate code appears in the display, press the up and down

buttons to adjust the desired values.

The mode structure is as follows:

Emissivity (EMS) adjustment

The Emissivity(EMS) is digitally adjustable from 0.10 to 1.0, by means of the up and down buttons..

LOCK on/off

Lock mode is particularly useful for continuous monitoring of temperatures. Press the up / down buttons

to turn this mode on or off. Press the measurement trigger to confirm lock mode. The IR thermometer will

continuously display the measured temperature until the measurement trigger is applied again. In lock

mode, press the up / down buttons to adjust the emissivity.

HAL / LOW on/off

Press the up or down button to turn the high / low alarm on or off. Pull the measurement trigger to

confirm.

HAL / LOW

The high / low alarm can be set to a value between -50 and 1000 °C (-58 …1832 °F).

Selection of measurement unit

Select the desired temperature unit (°C or °F) using the

°C/°F switch ①the location of which can be seen in the

picture.

Manual

Measurement

①Hold the meter by its handle and point the IR sensor towards the surface to be measured.

②Pull and hold the trigger to turn the meter on and start the measurement. The display will light up if the

battery voltage is sufficient. Replace the battery if the display does not light up.

③Release the trigger and the HOLD icon will appear in the LCD indicating that the reading is being held.

In HOLD status, press the UP button to turn the laser on or off. Press the DOWN button to turn the

backlight on or off.

④The meter will automatically power off after approximately 7 seconds after the trigger is released

(unless the device is locked to stay on).

Note: The meter automatically compensates for deviations in the ambient temperature. Please bear in

mind that it will take up to 30 minutes to adapt to a new ambient temperature. When you want to

measure two very different temperatures, please allow some time (several minutes) between the low

temperature and the high-temperature measurement.

Hot spot location

To find a hot spot, aim the thermometer outside the area of interest, then scan across with an up and

down motion until you locate the hot spot.

Battery replacement

①When the remaining battery voltage is not sufficient, the LCD will display “ ” which means that

replacement by a new 9 V battery is required.

②Open the battery compartment cover, then remove the battery and replace it by a new 9 V battery. Re-

attach the battery compartment cover.

7 Disposal

For the disposal of batteries, the 2006/66/EC directive of the European Parliament applies. Due to the

contained pollutants, batteries must not be disposed of as household waste. They must be given to

collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re-use them or

give them to a recycling company which disposes of the devices in line with law.
