Frequently Asked Questions - KM330 Comark

How to turn on and off the Comark KM330 thermometer?

Press the On/Off button on the housing. To turn it off, hold the button for 2 seconds or wait for auto-off after 10 minutes of inactivity.

What battery does the Comark KM330 use and how to change it?

The thermometer works with a LR03 (AAA) 1.5 V battery. To change it, open the battery compartment on the back of the housing using a Phillips screwdriver, replace the old battery, then close carefully.

How to use the hold function?

During measurement, briefly press the Hold button to freeze the displayed value. The 'HOLD' icon appears. Press again to release and resume real-time measurement.

How to view Min and Max values?

Press the Min/Max button to display successively the minimum temperature, maximum temperature and current temperature. The values are cleared each time the power is turned off.

What is the temperature range of the KM330?

The thermometer measures from -50 °C to +300 °C. Do not exceed these limits to avoid damaging the probe.

How to clean the thermometer probe?

After each use, wipe the probe with a soft cloth soaked in isopropyl alcohol or a food-safe disinfectant. Never immerse the housing in water.

The thermometer displays 'LO' or 'HI', what to do?

Display 'LO' indicates a temperature below -50 °C, 'HI' above 300 °C. Remove the probe from the extreme environment and let it return to ambient temperature.

How to perform an accuracy check?

Place the probe in an ice-water mixture (0 °C) or boiling water (100 °C). The display should show 0.0 °C ±0.3 °C or 100.0 °C ±0.3 °C. If not, recalibrate or contact support.

Can I use another probe with the KM330?

It is recommended to use only the type K probe supplied by Comark. Using an incompatible probe may affect accuracy or damage the device.

What to do if the display is dim or flashing?

A dim display indicates a low battery. Replace it as soon as possible. If the problem persists, check the battery contacts.

OPERATING INSTRUCTIONS

1. GENERAL INFORMATION

It is recommended that you read the safety and operation instructions before using this instrument.

WARNING

TO AVOID ELECTRIC SHOCK DO NOT ALLOW ANY PROBE OR SENSOR TO COME INTO CONTACT WITH LIVE ELECTRICAL POWER CONDUCTORS WITH VOLTAGES IN EXCESS OF 30V AC RMS OR 60V DC.

TO AVOID DAMAGE OR BURNS, DO NOT MAKE TEMPERATURE MEASUREMENTS IN MICROWAVE OVENS.

THE ⚠ SYMBOL ON THE INSTRUMENT INDICATES THAT THE OPERATOR MUST REFER TO THE WARNINGS GIVEN HERE.

CAUTION

Temperature Measurement Probes

This precision instrument has been designed for use with the extensive range of Comark temperature probes. The use of other probes may impair the performance and accuracy of the instrument. Full details of Comark probes and sensors can be obtained from Comark Customer Support department or your local distributor.

Repeated sharp flexing can break thermocouple probe leads. To prolong lead life, avoid sharp bends or kinks in the leads, especially near the connector.

This instrument complies with the Electromagnetic Compatibility Directive EN 61326-1.

Declaration of Conformity available. Contact Comark Customer Support or your local Distributor.

In line with its policy of continuous development, Comark Instruments reserves the right to alter the instrument specification without prior notice. Further information is available from Comark Instruments or your distributor.

2. CALIBRATION, CERTIFICATION AND SERVICE

No. 0451

Certification

Comark can provide certificates of calibration for its whole product range, to suit ISO 9000 and other quality assurance procedures, food hygiene regulations, HACCPs and environmental regulations. Comark certificates are produced by independent quality controlled processes which compare product performance against agreed National Standards. For peace of mind and best practice Comark recommend annual certification/recalibration.

Two levels of certification are available for infra-red temperature and non temperature instruments, excluding humidity:- UKAS certificates via an external accredited laboratory and NPL traceable certificates from the Comark calibration laboratory.

Three levels of certification are available for contact temperature and humidity products and these are detailed here:

a) UKAS Temperature Certification

The Comark UKAS (United Kingdom Accreditation Service) accredited temperature calibration laboratory is one of the finest in the UK. Comark UKAS certificates can offer the lowest uncertainty of 0.01°C and provide independent proof of correct calibration using equipment and procedures audited by UKAS inspectors. The equipment used is fully traceable to the National Physical Laboratory.

b) UKAS Humidity Certification In addition to the Comark temperature laboratory, the humidity laboratory continues the tradition of high accuracy certification and a wide range (25% to 90%RH) with uncertainties of 2.8% of reading. This range also includes Dew point measurements.

c) NPL Traceable Certification

Comark NPL certificates are traceable to the National Physical Laboratory and can offer uncertainty as low as 0.3°C.

Conformance

Certificates of conformance can be supplied for new, serviced and recalibrated instruments. These confirm that instruments are within their original manufactured specification.

Service/Repairs

Regular servicing and any required repairs, under warranty or after, are available from the Comark Service Department.

For more information on all Comark certification, calibration and service facilities please call Comark Customer Support or contact your local distributor.

3. INTRODUCTION

This instrument is a portable 3^-1/2 digit, compact-sized digital thermometer designed to use external type-K thermocouples as temperature sensors. It is compatible with the full range of Comark type-K thermocouple probes.

4. OPERATING INSTRUCTIONS

4.1 Selecting the Temperature Scale

Readings are displayed in either degrees Celsius (°C) or degrees Fahrenheit (°F). When the thermometer is turned on, it is set to the temperature scale that was in use when the thermometer was last turned off. To change the temperature scale, press the °C or °F key.

4.2 Selecting the Display Resolution

The thermometer allows two choices of resolution

High resolution: 0.1°C or 0.1°F

Standard resolution: 1° C or 1° F

To select the alternate display resolution, press the corresponding “1°” or “0.1°” key.

4.3 HOLD Mode

Pressing the HOLD key to enter the Data Hold mode, the “D-H” annunciator is displayed. When HOLD mode is selected, the thermometer holds the present reading and stops all further measurements.

Pressing the HOLD key again cancels HOLD mode, causing the thermometer to resume taking measurements.

4.4 MAX Mode

Press the MAX key to enter the MAX mode. The thermometer then records and updates the maximum value and the MAX annunciator appears on the display. Press the MAX key again to exit the MAX recording mode. In the MAX mode, press HOLD key to stop the recording, press HOLD again to resume recording.

The maximum function is limited to use on a single temperature scale at a time and for readings which do not make a transition through zero.

5.1 Battery Replacement

Power is supplied by a 9 volt, PP3 battery. The battery sign appears on the LCD display when a replacement is needed. To replace the battery, remove the three screws from the back of the instrument and lift off the front case. Exchange the battery in the protection tube located at the top of the rear cover. Replace the instrument front squarely with the rear cover and secure with the three screws.
