1.5 Battery Installation/Replacement
Four 9 V batteries are supplied with the 190I. The battery compartment is located on the back of the
instrument. The compartment will hold up to four batteries but only one battery is necessary to operate
the instrument. Use the following procedure to install/replace the batteries:
To prevent battery leads from shorting on the
battery compartment's conductive coating, ensure
that all four batteries are INSTALLED at all times.
Unit power must be left ON and batteries replaced
one at a time to prevent data loss when the log
mode is activated and logged data is to be
retrieved.
1. Loosen the two-quarter turn fasteners securing the battery compartment cover to the back panel.
2. Remove the battery compartment cover to gain access to the batteries.
3. Replace the batteries one at a time, observing proper polarity.
The unit may make beeping sounds while inserting
the batteries.
4. Replace the battery compartment cover, securing it with the two-quarter turn fasteners.
1.6 Power
The 190I is powered using four 9 V batteries. The batteries (four) are housed in a separate compartment
accessed from the instrument back panel. All four 9 V batteries are required to operate the unit for
approximately 200 hours. Visual and audible low battery indications are provided whenever battery power
is low (four minute intervals for the audible and continuous for the visual after a battery test).
