1.2 How to Operate And Maintain Unit
• Battery Operation
If and „bAt“ in lower display are shown, the battery has been used up and needs to be replaced. The device
will, however, continue operating correctly for a certain time.
If ´bAt´ is shown in the upper display the battery has been completely used up.
Hint: We recommend to take out battery if device is not used for a longer period of time!
• Mains Operation
Attention: When using a power supply unit please note that operating voltage has to be 10.5 to 12 V DC. Do not
apply overvoltage!! Simple 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 plug power supply with the mains supply make sure that the operating voltage stated at the
power supply is identical to the mains voltage.
• Treat device and probes carefully. Use only in accordance with above specification. (do not throw, hit against etc.).
Protect plugs and sockets from soiling.
• 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!
• Selection of Output-Mode: The output can be used as serial interface or as analogue output. This choice has to
be done in the configuration menu. If no output is needed, we recommend to switch it ‚off‘, the battery life then is
nearly twice as long as with serial or analogue output.
1.3 Connections
1. Output
Operation as interface: Connect to optically isolated interface adapter
(accessory: GRS 3100 or GRS3105)
Operation as analogue output: Connection via suitable cable.
Attention: The output mode has to be configured (p.r.t 2.7) and influences
battery life!
2. Probe connection
3. The mains socket is located at the left side of the measuring instrument.
1.4 Display Elements
1 = Main display: Currently measured temperature
2 = Secondary display: Display of min, max or hold values
Special display elements:
3 = Warning triangle: indicates a low battery
4 = Corr-arrow: indicates that correction factor is activated
5 = Offset-arrow: indicates that zero point offset (offset) is
activated.
6 = Min/Max/Hold: shows if a min., max. or hold value is displayed
in the secondary display.
1.5 Pushbuttons
button 1: On/Off key
