F. Menu 6 is used to select by which keying method faster pressurization and venting rates are
obtained. Pressing the START key gives access to the Rate Toggle Mode screen. Pressing
SEL from this screen gives access to the Normal Rate Mode. Pressing SEL again returns to
the Rate Toggle Mode. The Normal Rate Mode is the default mode and the faster rate during
pressurization is obtained by pressing and holding down the START key (or the STOP key
during venting). If the Rate Toggle Mode is selected, the START key (or STOP key) is used
with discrete presses to toggle between the normal and fast rates.
To return to the Maintenance Menu 6 screen press the STOP key.
CAUTION: THE FAST RATE SHOULD BE USED WITH CARE WHEN
OPERATING IN THE STATIC MODE (REFER TO PARAGRAPH 5.M)
Menus 4 and 5 are not used by the Operator. For further information on the use of Menus 2 and 3,
refer to Calibration.
To exit the Maintenance Mode, the STOP key is pressed.
9. BATTERY REPLACEMENT
WARNING:
THE MATERIALS USED IN THE CONSTRUCTION OF ALKALINE
MANGANESE DIOXIDE BATIERIES ARE CORROSIVE AND MAY CAUSE
BURNS TO EYES OR SKIN IF THE BATIERIES ARE PUNICTURED IN
ANYWAY. IN CASE OF CONTACT, RINSE AFFECTED AREA
MMEDIATELYWITH PLENTY OF WATER AND SE~EK MEDICAL ADVICE.
ADDITIONALLY, MANGANESE DIOXIDE IS HARMFUL WHEN INHALED
(WHEN DRY) AND IF SWALLOWED. IN CASE OF ACCIDENT SEEK
MEDICAL AID IMMEDIATELY.
A. General
The recommended batteries for use with the PSLT are Duracell LR6 Alkaline Manganese
Dioxide Batteries (also known as Size AA or MN1500). Their normal operating voltage range
is 1.5Vto 1V per cell under most conditions of PSLT expected load and operating
environmental temperature.
The PSLT has demonstrated an operational battery life in excess of 3 hours under the
following conditions:
(1) Pump continuously running at maximum rate.
(2) All electronic circuits fully operational
(3) Display operating
Initial battery status is displayed at power up by means of a battery symbol shown briefly
during the period the system performs an internal self-diagnostic test routine. It provides an
estimate of battery energy shown as a percentage from 20% to 100% in steps of 20%.
When the combined battery voltage drops below 10V, the BATT LOW flag gives a flashing
illumination, indicating that the PSLT has approximately 15 minutes running time remaining
(the actual value depends on the individual batteries and also the number and type of tests
carried out previously).
