Product Specifications, Alarms and Delays
You can enter specification limits for each of the products you have defined, at each critical
process/location, in either the Products panel, or the Processes/Locations panel. An upper
specification is the maximum allowable temperature for a product at a given process/location, and a
lower specification is the lowest allowable temperature at the given process/location.
The software will indicate when and which readings have been recorded that are above or below
these values when viewing the reading data. For information on viewing readings, and how the
specification values affect the display of readings in the software, see Chapter 7, Accessing Data
Stored in the ThermoCheck.
Additionally, you can set alarms for a product at a process/location for the upper and/or lower
specification values. When alarm condition has been violated (when a reading is above the upper
specification value or below the lower specification value) the unit will beep and display an alarm
symbol on the display.
You can set specification values to match your organisation's quality control specifications. Note that
the specifications for a product may vary widely between processes/locations, for example:
• mince pies, in the freezer, might have an upper and lower specification of –20°C to –15°C
respectively,
• but during cooking, the upper and lower specification may be 160 °C to 180°C.
The unit also supports a probe reading storage delay at each process/location for a product. A
reading storage delay is useful in situations where the temperature of the product may require time to
stabilise to ensure a fair and accurate reading is recorded. Setting a reading storage delay value
ensures that when a reading is taken, whoever the operator is, the sensor is given enough time to
record an accurate reading. If a reading storage delay is configured for a product at a
process/location, the display will flash WAIT, and the unit will sound a series of beeps, for the
configured reading storage delay, before storing the reading.
To set up the specifications for a product, in the Products panel:
• Select the appropriate process/location, under the chosen product.
• Enter the upper and lower specification values in the Upper and Lower boxes, in the
Specifications group, in the panel to the left of the tree view.
• If you require an alarm on the upper or lower specification, tick the appropriate checkbox(es) in
the Alarms group.
• If the probe will need a reading storage delay, enter this in Reading Storage Delay. This delay is
specified in seconds.
The process is the same for setting specifications in the Processes/Locations panel, except that the
first step involves selecting the product under the chosen process/location (as opposed to the other
way around).
