To select a menu item or to change parameters within the menu items, use the arrow keys at the side of the meter. To confirm a change or to open a menu item, press the key. The settings are arranged as follows:
| Menu | Display | Possible settings |
|---|---|---|
| Set type of thermocouple | TYPE | K and J |
| Offset | OFFSET | Range ±5.0 °C / ±9.0 °F |
| Auto Off | SLP | ON and OFF |
Note: As long as the MIN MAX AVG function is activated, you cannot enter
the menu.
6.1 Change type of thermocouple
If the connected type of thermocouple is different from the type shown in
the lower left-hand side of the display, the meter’s thermocouple setting must
be changed accordingly. To do so, enter settings mode and change the type as
required. Thermocouples of the types K and J can be connected.
6.2 Set offset
When the accuracy is outside the specifications, an offset can be carried out.
The possible range for the offset is ±5.0 °C / ±9.0 °F. To be able to set the
offset, first connect the meter to the thermocouples. Then place the
thermocouples into a liquid of known temperature, for instance ice water. Now
wait for the displayed reading to stabilise. Then go to the settings and
change the offset until the displayed reading equals the value of the
reference liquid. Offsets must be set for each channel individually.
6.3 Automatic Power Off after 20 minutes of inactivity. To disable this
function temporarily, enter the settings. In the menu item “SLP“, you can
disable this function.
ON = enabled, OFF = diabled
Note: Everytime the meter is powered on, this function will be enabled
automatically.
Thermocouples
If you want to use thermocouples, connect these via the connectors at the
upper side of the meter.
Observe correct polarity. Now power on the meter. After approx. a second, a
reading will be displayed. If no thermocouple is attached for a channel, “- –
– -‘‘ will be displayed. When the reading is exceeded, “OL“ will be displayed.
With the key, you can select T1, T2 or T1 – T2 to be shown in the primary or
secondary display.
Note: Ensure that you have set the correct type of thermocouple. The type
of thermocouple can be changed in the settings. The current thermocouple is
shown in the lower left-hand part of the display.
Hold reading
To hold the currently displayed reading, press the key during the measurement. “HOLD“ will be displayed. While “HOLD“ is displayed, the key will be active. To continue the measurement, press the key again.
MIN / MAX / AVG
The temperature meter has the following measuring functions:
| Name | Description |
|---|---|
| MIN | Shows the lowest reading |
| MAX | Shows the highest reading |
| AVG | Shows the average value |
To activate one of these functions, press the key. “REC“ will appear in the
display along with the function you set. The current reading will only be
shown in the primary display now. In the secondary display, the respective
value of the measuring function will be displayed. At the same time, the
measurement period will start, which will show you when the value has been
determined. You can switch between the different measuring functions at any
time. All values are determined continuously. To leave this function, press
and hold the key for three seconds.
Note: After leaving this measuring function or when the meter is turned
off, the saved readings will be lost.
Replacing the batteries
As soon as the battery icon appears in the display, the batteries must be replaced to make sure the meter works in line with its specifications. To replace the batteries, first turn off the meter. Then open the battery compartment at the rear side. Replace the batteries by three new 1.5 V AAA batteries, observing correct polarity. The meter is ready to be used again after closing the battery compartment.

Disposal
For the disposal of batteries in the EU, the 2006/66/EC directive of the
European Parliament applies. Due to the contained pollutants, batteries must
not be disposed of as household waste. They must be given to collection points
designed for that purpose.
In order to comply with the EU directive 2012/19/EU we take our devices back.
We either reuse them or give them to a recycling company which disposes of
the devices inline with law.
For countries outside the EU, batteries and devices should be disposed of in
accordance with your local waste regulations.
If you have any questions, please contact PCE Instruments.
