Frequently Asked Questions - 830T1 Testo

How to turn on and off the Testo 830T1?

To turn on the device, press the measurement button. The screen lights up and the backlight is active for 10 seconds. To turn off, hold the button until the screen turns off. The device shuts off automatically after 1 minute of inactivity.

How to perform an infrared measurement?

Hold the measurement button down. Aim the laser dot at the object. Measurements appear (2 per second). Release the button to freeze the value (Hold). Min/max values are displayed. For a new measurement, press again.

What to do if the screen shows '---'?

In infrared mode, '---' indicates that the measured temperature is out of range (-30 to +400 °C). Check that the object is in range. If the problem persists, clean the lens.

How to adjust the emissivity?

In infrared mode, press the © key to enter adjustment. Use the arrow keys to adjust emissivity (0.1 to 1.0). The device automatically returns to measurement mode after 3 seconds of inactivity.

How to replace the battery?

Turn off the device. Open the battery compartment by removing the cover. Replace the used battery with a new 9 V battery respecting polarity (+/-). Close the cover.

How to clean the lens?

Use a cotton swab moistened with water or medical alcohol to gently clean the lens. Do not use abrasive solutions. For the housing, a damp cloth is sufficient.

What is the optical ratio of the 830T1?

The optical ratio is 10:1, which means at 10 cm distance, the measurement area is 1 cm in diameter (90% of energy). The larger the distance, the wider the measured area.

What is the measurement accuracy?

The accuracy is ±1.5 °C or 1.5% of the measured value for temperatures from 0.1 to +400 °C, and ±2 °C or 2% for temperatures from -30 to 0 °C (at 23 °C ambient).

Can I measure shiny metal surfaces?

Shiny metals have low emissivity, making infrared measurements inaccurate. To improve measurement, apply emissivity adhesive tape (ε=0.95) to the surface. Otherwise, use a contact thermometer.

What to do when a low battery indicator is displayed?

If the backlight no longer works or the low battery icon appears, replace the 9 V battery as soon as possible. If the device does not turn on, the battery is dead.

11. Information on infrared measurement

11.1 Measurement method

Infrared measurement is an optical measurement

• Keep lens clean.
  Do not measure with clouded lens.
• Keep measurement field (area between instrument and object being measured) free of interferences: no dust and dirt particles, no moisture (rain, steam) or gases.

Infrared measurement is a surface measurement

If there is dirt, dust, frost etc. on the surface, only the top layer will be measured, i.e. the dirt.

In the case of shrinkwrapped foodstuffs, do not measure in air pockets.
If values are critical, always subsequently measure using a contact thermometer. Particularly in the food sector, the core temperature should be measured with a penetration/immersion thermometer.

Adaptation time

If the ambient temperature changes (change of location, e.g. inside/outside measurement) the instrument needs an adaptation time of 15 minutes for infrared measurement.

11.2 Emissivity

Materials have different emissivities, i.e. they emit different levels of electromagnetic radiation. The emissivity of testo 830 is set in the factory to 0.95. This is the ideal value for measuring nonmetals (paper, ceramics, plaster, wood, paints and varnishes), plastics and food

Bright metals and metal oxides are only suited to a limited extent to infrared measurement on account of their low or nonuniform emissivity.

• Apply emissivity enhancing layers such as varnish or emission adhesive tape (Item no. 0554 0051) to the object being measured. If this is not possible, measure with the contact thermometer.
