Damage or injuries caused by non-observance of the manual are excluded from our liability and
not covered by our warranty.

• The device must only be used as described in this instruction manual. If used otherwise,
this can cause dangerous situations for the user and damage to the meter.

• The instrument may only be used if the environmental conditions (temperature, relative
humidity, …) are within the ranges stated in the technical specifications. Do not expose
the device to extreme temperatures, direct sunlight, extreme humidity or moisture.

• Do not expose the device to shocks or strong vibrations.

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

3.16 Capturing Minimum and Maximum Values

The MAX MIN record mode captures
minimum and maximum input values. When
the input goes below the recorded minimum
value or above the recorded maximum value,
the multimeter beeps and records the new
value. This mode is for capturing intermittent
readings, recording minimum and maximum
readings unattended or recording readings
while equipment operation precludes
watching the meter. To activate MAX MIN
mode, press soft key labelled ◄. If the meter
is already in MAX MIN function, pressing ◄
causes the meter to turn off MAX MIN
function.

To activate the relative mode, press the soft
key labelled ▲. If the multimeter is already in
the relative function, pressing ▲ causes the
meter to turn off relative mode.

3.18 Capturing Peak Values

To activate peak mode, press the soft key
labelled ►. If the meter is already in the peak
function, pressing ► causes the meter to turn
off peak mode.

3.19 Non-Contact AC Voltage Detector (100 to 1000V AC)

: Risk of Electrocution. Before use,
always test the voltage detector on a known
live circuit to verify proper operation.

: Insulation type and thickness,
distance from the source, and other factors
may affect operation. Always verify live
voltage using other methods before working
on electrical circuits.

• The non-contact voltage detector operates
when the meter is set to any measuring
function. The detector does not operate
when Auto Power Off turns the meter off or
when the rotary function switch is set to the
off position.

• Slowly move the detector probe closer to the
conductor being tested.

• If AC voltage within the specified range is
present, the indicator light will illuminate.

NOTES: The detector is designed with high
sensitivity. Static electricity and other sources
of electrical energy may randomly activate
the detector. This is normal operation. The
detector only activates the indicator light
when AC voltage is present. It does not
indicate the voltage level on the LCD.

4.2 Using the thermal imager

For basic operation, follow these steps:

1. Set the function switch to any position.

2. Press the “IR” button to switch ON the thermal imager. Target the object with the thermal imager
lens.

3. The display will show the temperature measurement in the upper left hand corner for the
targeted area along with the currently selected emissivity value.

4. In thermal imaging mode, the laser pointer and display cross hairs can be used to assist in
targeting. These tools can be switched ON or OFF in the Setting menu.

5. In Thermal imaging mode, the highest temperature will be auto marked by a red cross and the
lowest temperature will be auto marked by a blue cross. This can be switched ON or OFF in the
Setting menu.

6. In Thermal imaging mode, the meter continues to operate normally as a multimeter, allowing
any of the electrical functions to be used.

7. Press the HOLD button to hold the thermal image frame, then press and hold the HOLD button.
You will capture the screen and save a bitmap with measurement data to the SD card. The
saved bitmap can be analysed later by the PC software or smartphone APPs.

8. The thermal imager’s FOV (Field of view) is 21 x 21 degrees.

9. FOV is the largest area that your imager can see at a set distance.

10. The following chart lists the horizontal lFOV, vertical FOV and IFOV for lens:

Focal length

Horizontal FOV

Vertical FOV

IFOV

7.5 mm

21 °

21 °

4.53 mrad

IFOV (Instantaneous Field of View) is the smallest detail within the FOV that can be detected or
seen at a set distance. The unit is rad. The formula is:

IFOV = ( Pixel Size )/ ( Lens focal length )

D:S

theoretical

( = 1/ IFOV

theoretical

) is the calculated spot size based on the pixel size of the thermal

imager detector array and lens focal length.
Example: If the thermal imager uses a 9 mm lens because the pixel size of the detector is 34µm,

horizontal FOV is 21°, vertical FOV is 21°, the IFOV is 34µm/7.5mm = 4.53mrad;
D:S

theoretical

( = 1/ IFOV

theoretical

) = 220:1

D:S ( = 1/ IFOV ) is the spot size needed to provide an accurate temperature measure. Typically,
D:S

measure

is 2 to 3 times smaller than D:S

theoretical

, which means the temperature measurement
area of the target need to be 2 to 3 times larger than that determined by the calculated theoretical
D:S.

10 Disposal

For the disposal of batteries in the EU, 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.

For countries outside the EU, batteries and devices should be disposed of in accordance with
your local waste regulations.

If you have any questions, please contact PCE Instruments.
