4. Design and function
4.2.9 USB communication interface connector
The USB connector is fitted as standard. Communication requires the installation of the
USB driver on a PC. See the separate information supplied on the CD. A standard USB
cable is supplied with the CTH7000.
The instrument can be used with the ULOG program (supplied on the CD) or simply used
to transmit ASCII data, which may be recorded using a simple terminal program.
Communication via an USB cable connected to a PC may cause the
CTH7000 to be noisy. WIKA can accept no responsibility for any performance
degradation when connected to a PC.
4.3 Instrument operating modes
The instrument has two operating modes.
■
Measurement mode which displays the measurement readings and status information.
■
Menu mode which lets you select and alter the instrument operation and its settings.
4.3.1 Measurement mode
In measurement mode, the LC displays the current reading (temperature or resistance),
the unit symbol, the channel and type of sensor selected (and conversion method); the
time of day is also shown.
⇒
The time will be replaced by ‘Logging’ or ‘Remote’ when these modes are selected.
This is the normal operating display for the CTH7000. The display will look similar to the
