About these instructions and symbol descriptions
Incorrect operation can lead to serious injury or death.
Incorrect operation or negligence may result in personal injury,
damage to the equipment or faulty measurements.
Instructions and tips for operation.
Numbers in the figures (1, 2, 3 ...) refer to the corresponding numbers in brackets
(1), (2), (3) ... in the text next to the item numbers in the tables.
Instructions for which the order must be followed are numbered (1, 2, 3, ...).
Lists are marked with bullet points (●, ●, ...).
2 Safety information
2.1 General safety instructions
•Piease read carefully the Operation Manual before operating the instrument
•Don't cleanse the temperature measuring instrument with any solvent
•Safety symbols
Important notices against hazards:
Compliant with European CE safety directive
This instrument complies with the standards provided below:
EN61326-1
EN60825-1
Laser must be prevented from aligning itself towards human eyes or
reflective surfaces.
3 Important notices
When the working environment experiences a sudden change, the temperature
measurement meter must be placed in an environment for 30 minutes. The
measurement can be resumed only when the temperature inside the meter is
consistent with that outside it.
The electromagnetic field from electric welding and inductive heating must be
minimized
Don't put the temperature measurement meter close to or onto a hot object.
The meter must be kept clean so that dust is denied access to lens cone.

6 Mesurement method
1. Set the upper limit value for alarms:
Press trigger + mode key to set the status for the instrument switch Mode key to the upper
limit set for an alarm. At this moment, the instrument's functional indication area shows
HAL and secondary display panel the upper limit for an alarm. Press key to increase or
decrease alarm value. A long press on the key will mean rapid increase or decrease in
the set value.
The default alarm value for this instrument is 800°C.
2. Set low alarm value for the instrument
Press trigger + mode key to set the status for the instrument switch Mode key to the low
limit set for an alarm. At this moment, the instrument's functional indication area shows
HAL and secondary display panel the low Iimit for an alarm. Press key to increase or
decrease alarm value. A long press on the key will mean rapid increase or decrease in
the set value. The default alarm value for this instrument is -50°C.

3. Set the emissivity for the instrument
Press trigger + mode key to set the emissivity for the instrument, switch Mode key to the
low limit set for an alarm. At this moment, the instrument's functional indication area shows
and secondary display panel the emissivity for an alarm. Press key to increase or
decrease emissivity value. A long press on the key will mean rapid increase or
decrease in the set value.

4. Set the temperature unit fur the instrument
Press the Mode key for 2 seconds to switch the temperature measurement unit.
5. Enable/disable Laser
Press key to enable or disable laser.
The instrument will display the symbol for laser
6. Turn on or off UV
Press key to turn on or off UV (only PM6530C). Leak detection:
The Leakage of verhicle air conditioning and other high pressure systems can be detected
quickly by ultraviolet. Flourescent agent is injected into the air condition system, fluorescent
agent will with the refrigerant in the air-conditioning system in circulation, when the air
conditioning system has a leak, fluorescent agent will left leakage Fluorescence leakage
under theirradiation of ultraviolet light can emit fluorescence at, and then find the leak.
7. Non-contact temperature measurement
Target the temperature measurement meter at an object and pull the trigger for a period to
carry out continuous measurement of temperature. After display becomes stable, release
the trigger to hold measurement result.
When the trigger is pressed, the instrument’s secondary display
panel will first show the set emissivity and then display the
measured maximum temperature.

When the measured value is greater than ambient environment + HAL value or less than
the ambient environment + LAL value, the red indicator of the instrumentwill be on to
sound an alarm .Otherwise, the green indicator will be on.
8. K-type Temperaturemeasurement
After K type thermocouple probe is inserted into the thermocouple socket of the instrument,
the instrument's functional indication area will display PRb and secondary display panel the
temperature value of K thermocouple.

7 Proportion between the distance from probe to object
and the diameter of the object to be measured (D:S)
Temperature measurement meter has a certain angle and field of vision, as shown in the
diagram below:
It must be ensured that the object to be measured is fully within the field of vision afforded
by the temperature measurement meter, that is, the meter can see nothing but the object
to be measured. The greater the object to be measured is, the farther the distance detected
by the meter may be. The smaller the object is, the shorter the distance to be measured
must be. The proportion between the distance to be measured and the size of the object to
be measured (D:S) is 12:1, as shown in the diagram below.
While measuring an object, the instrument will emit an indicative ring. The measured
temperature of the surface is the internal temperature of the ring.
