Installation

Install the batteries

W A R N I N G

Explosion hazard. Incorrect battery installation can cause the release of explosive

gases. Be sure that the batteries are of the same approved chemical type and

are inserted in the correct orientation. Do not mix new and used batteries.

N O T I C E

The battery compartment is not waterproof. If the battery compartment becomes

wet, remove and dry the batteries and dry the interior of the compartment. Check

the battery contacts for corrosion and clean them if necessary.

N O T I C E

When using nickel metal hydride (NiMH) batteries, the battery icon will not

indicate a full charge after freshly charged batteries have been inserted (NiMH

batteries are 1.2 V versus 1.5 V for alkaline batteries). Even though the icon does

not indicate complete charge, 2300 mAH NiMH batteries will achieve 90% of

instrument operation lifetime (before recharge) versus new alkaline batteries.

N O T I C E

To avoid potential damage to the meter from battery leakage, remove the meter

batteries prior to extended periods of non-use.

The meter can be powered with AA alkaline or rechargeable NiMH

batteries. To conserve battery life, the meter will power off after

5 minutes of inactivity. This time can be changed in the Display Options

menu.

For battery installation, refer to Figure 1.

Note: A tool such as a flat screwdriver may be necessary the first time the cover is

removed.

Make sure that the cover is tightly closed to maintain the IP67 enclosure

rating.

Startup

Turn the meter on and off

N O T I C E

Make sure that the probe is connected to the meter before the meter is turned on.

Push and hold to turn on or turn off the meter. If the meter does not

turn on, make sure that the batteries are properly installed.

Note: The meter is set to automatically power off after 5 minutes of inactivity to

maximize the battery life.

Operation

D A N G E R

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.

W A R N I N G

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.

C A U T I O N

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:

Disconnect time Polarization time

< 5 minutes 10 minutes

5 to 15 minutes 45 minutes

> 15 minutes 6 hours
