2.2 Product overview
Pacemaker precautions. The instrument has an internal magnet. Keep the instrument a
minimum of 5 cm (2 in.) from the user. A magnetic field can:
• Stop the stimulating pulses from the pacemaker that control the rhythm of the heart.
• Cause the pacemaker to supply the pulses irregularly.
• Cause the pacemaker to ignore the rhythm of the heart and supply pulses at a set
interval.
The automatic cleaning module is an accessory for the TU5300 sc and the TU5400 sc turbidimeters.
Refer to Figure 1. The automatic cleaning module cleans the vial at a selected time interval or
turbidity reading limit. As an alternative, start the cleaning manually or with a Modbus connection.
