Calibration

To ensure the accuracy of measurement of the temperature data logger, it is suggested to calibrate it regularly (usually once a year). The calibration should be done by professionals, according to the procedure described in this manual.

Note:
The instrument has been calibrated before shipment.

Preparation for calibration
Before calibration, please prepare the test environment as below:

The required temperature of the shielded calibration room is +23 °C ±0.3 °C (+73.4 °F±0.5 °F)

In order to achieve a stable reference room temperature point, the PCE-T 394 must be placed in the calibration room for more than one hour before the calibration.
In order to make a zero point calibration, two iron or copper thermocouple connectors are also required (short connect the positive and negative inputs).

Cold-junction compensation calibration

Enter setup mode and press the keys until the icon is displayed and at the same time, the inner NTC temperature value of the cold-junction compensation temperature is displayed.
Press thekey to enter calibration mode.
Press until the inner NTC temperature value is the same as the room temperature and then press the key to confirm.

AD value calibration (only to be carried out by PCE Instruments)

Plug the thermocouple connectors into the T1 and T3 connections so that the positive and negative poles are short circuited.
Press both the and the key at the same time. At this time, the icons (flash) on the LCD.

Press the key to calibrate the AD value. If you need to cancel, press and hold the key.

Warning:
This calibration must only be carried out by PCE Instruments.

Maintenance and cleaning

Cleaning and storage

The white plastic sensor dome should be cleaned with a damp, soft cloth, if necessary.
Store the temperature data logger in an area with moderate temperature and relative humidity.

Charging the battery
When the battery power is insufficient, the battery icon appears on the LCD and flashes. Use the DC 5V power adaptor to connect to the micro USB charging port at the bottom of the meter. The battery icon on the LCD indicates that the battery is charging and will disappear when the battery is fully charged.
