Using the ThermoCheck

Using the ThermoCheck for the First Time

If your ThermoCheck is turned off, you can turn it on by pressing any key on the keypad, or by attaching external power, or by connecting a computer. When a ThermoCheck is powered up, the battery voltage, along with the firmware version, will be shown on the display. This power-up screen is shown every time the unit is turned on, or the configuration settings are viewed or changed (see Customising Without Using the Software, in Chapter 5, Customising the ThermoCheck, for information on updating the unit’s settings).

“No database” is also displayed on the power-up screen if the unit does not have a database installed. If a database has been preloaded in the unit, the number of free readings will be displayed. In addition, there may be a description of the ThermoCheck at the top of the screen. You can set or change this description in the software (see Customising With the Software, in Chapter 5, Customising the ThermoCheck).

After two and a half seconds, the display will show the ThermoCheck’s current date and time along with the current temperature, if the sensor probe is plugged in. If a user is logged on, this screen will also display the name (or description) of the user that is currently logged on.

When the unit’s battery requires charging or replacement, an empty battery symbol will flash in the top right-hand corner of the display screen. If the batteries are rechargeable, you can charge them by connecting external power and by ensuring that the Recharge option is enabled (see Customising Without Using the Software, in Chapter 5, Customising the ThermoCheck). While the battery is charging, the battery symbol in the top right of the display screen will repeatedly fill with black. When the battery has completely charged the symbol will disappear.

A ThermoCheck requires a database before it is able to take any readings. Please refer to Chapter 3, Setting Up a Database, for further information about creating and uploading databases to the ThermoCheck.

Selecting a Product and Process/Location

Before taking a product’s reading, you first need to install a database in the unit to store the different products and processes/locations. Processes/locations refer to the various stages in the production of a product at which you are interested in monitoring the product’s temperature, to ensure (for example) that quality control guidelines are met.

For information on defining a product and process/location database, refer to Chapter 3, Setting Up a Database. Once you have a database relating products and processes/locations stored in the unit, you can select products and processes/locations and then record temperature readings.

In addition, if you want to store an operator’s name with a reading, you will need to install a user list in the unit. For information on user lists, refer to Chapter 4, Setting Up a User List. If a user list has
