3 Product Specification
3.1 Scope of delivery
The scope of supply includes:
•
Device with battery
•
Operating manual
3.2 Operation and maintenance advice
•
Battery operation:
If ‘bAt’ is shown in the lower display the battery has been used up and needs to be
replaced. However, the device will operate correctly for a certain time. If ‘bAt’ is
shown in the upper display the voltage is too low to operate the device; the battery
has been completely used up.
The battery has to be taken out, when storing device above 50 °C.
We recommend taking out battery if device is not used for a longer
period of time.
After recommissioning the real-time clock has to be set again.
•
Mains operation with power supply
When using a power supply please note that operating voltage has to be
10.5 to 12 V DC.
Do not apply overvoltage!! Cheap 12V-power supplies often have
excessive no-load voltage.
We, therefore, recommend using regulated voltage power supplies.
Trouble-free operation is guaranteed by our power supply GNG10/3000.
Prior to connecting the power supply to the mains, make sure that the operating
voltage stated at the power supply is identical to the mains voltage.
•
Treat device and sensor carefully. Use only in accordance with above specification.
(do not throw, hit against etc.). Protect plug and socket from soiling.
•
Connecting/changing sensors
To disconnect thermocouple sensor plug do not pull at the cable but at the
plug
Selection of types of thermocouples:
Prior to carrying out a
measurement make sure to check if device is set to the thermocouple
type used (type is shown on the display shortly after unit has been
switched on). Unless the correct thermocouple is set, temperature
measurements will be incorrect!
