2.1 Repair or adjustment Equipment that is not covered by the warranty will, if possible, be repaired by Unisense with appropriate charges paid by the customer. In case of return of equipment please contact us for return authorization.
The meters offer temperature compensation for all amperometric channels with a range of ± 3°C from the calibration temperature. This will work if a temperature sensor is connected. The UniAmp meters are USB-powered and fully integrated with the Unisense SensorTrace Suite software, allowing any combination of Unisense electrochemical sensors and optode technology.
Configuration window Figure 2: Unisense UniAmp service in the Windows Notification Area. Click the up-arrow to show hidden icons, then click the UniAmp service icon to open it. Only channels with a sensor connected, will be shown. Here sensors for H S, pH and O connected and shown.
The UniAmp instruments are powered from the PC through the USB cable and are operated through the Unisense UniAmp service in the Notification Area (Figure 2). Just connect the UniAmp to the PC and settings for the connected sensors will be available in the UniAmp service window.

O sensor (see 7.3 Manually setting the sensor polarization). The 6 pin connector for the legacy Unisense Multimeter requires and adaptor to be used with the UniAmp instruments. If using sensors via adaptors, the sensor polarization has to be set manually, using the Unisense pop-up window residing in the Windows Notification Area (see 7.3 Manually...
The Analog out must be activated in the UniAmp service window (Figure 3). Contact sales@unisense.com if you need the adaptor. For connection to non-Unisense equipment, contact Unisense first, to avoid damage to the instrument. Figure 5: Connectors for Analog and Digital in and output and for the grounding cable (right).

The temperature use for correction may be: •...
Updates are important for keeping Windows secure. Therefore, if you choose to disable or delay updates, make sure to allow Windows to check for updates now and then. 13.1.2 Loss of connection to the UniAmp because of USB power saving Windows may turn USB connections off in order to save power.

In some cases, electrical noise is emitted from other equipment in the vicinity (constant temperature bath, air conditioning, oven etc.). Interference of this type will often be periodic, e.g. noise emitted when equipment is switching on or off. If such problems occur, try switching nearby equipment off one by one, to identify which equipment is generating the noise.
