Chemical exposure hazard. Obey laboratory safety procedures and
wear all of the personal protective equipment appropriate to the
chemicals that are handled. Refer to the current safety data sheets
(MSDS/SDS) for safety protocols.

Pacemaker precautions. If electromagnetic interference (EMI) occurs,
it can either:
• 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.
Current research shows that cellular devices are not a significant
health problem for most pacemakers wearers. However, persons with
pacemakers should use precautions to make sure that their device
does not cause a problem. Keep the device a minimum of 20 cm
(7.9 in.) from the user.

Electromagnetic radiation hazard. Make sure that the antenna is kept at
a minimum distance of 20 cm (7.9 in.) from all personnel in normal use.
The antenna cannot be co-located or operated in conjunction with any
other antenna or transmitters.
Setup for pH
The meter is ready for pH or ORP calibration without additional setup.
Setup for dissolved oxygen
Before a calibration or a measurement for dissolved oxygen, the probe
must be polarized and the settings for atmospheric pressure and salinity
must be entered.
Polarize the electrode
If the probe or batteries are disconnected, connect the probe or install
the batteries and wait for polarization:
