YSI 58 - Manual (Page 6)

SECTION 2 PREPARING THE METER
2.1 UNPACKING
When you unpack your new YSI 58 Dissolved Oxygen and Temperature System for the first time,
compare the packing list with the contents of the shipping box. If there is anything missing or
damaged, contact your YSI dealer from whom you purchased the YSI 58 or YSI Customer Service at
800-765-4974 or 937-767-7241.
2.2 WARRANTY CARD
Please complete the Warranty Card and return it to YSI. The warranty card allows the entry of your
purchase of this instrument in our computer system.
2.3 BATTERIES
Batteries provide complete portability; a battery eliminator feature bypasses the instrument batteries
for extended line-powered use (not including stirrer). Instrument batteries are carried internally in one
holder while a second holder allows internal installation of batteries for powering a submersible stirrer
for use in the field.
Instrument batteries are in the upper holder. Four D-size carbon-zinc batteries are used. The LOBAT
warning shows on the display when about 50 hours of use remain. This warning reminds the operator
to change batteries at their earliest convenience. Batteries may be removed when the instrument will
be used on a long-term basis for laboratory measurement powered by the YSI 5401 or 5402 battery
eliminator.
Stirrer batteries fit in the lower battery holder. Four D-size carbon-zinc batteries are used. When
about five hours or less of battery life remains, the LOBAT warning will show on the display when
the STIRRER control is held at the spring-loaded BATT CHK position. Instrument must be turned
on. Batteries are needed only when the YSI 5795A Submersible Stirrer will be used.
YSI 5401 (115 VAC) AND 5402 (230 VAC) BATTERY ELIMINATORS
For exclusive or long-term laboratory use, the 5401 or 5402 Battery Eliminator may power the YSI
58. When the battery eliminator is in use, batteries may be removed from the instrument battery
compartment (upper compartment).
Note: The battery eliminator does not power the 5795A Field Stirrer, which operates only when
there are batteries in the stirrer battery compartment (lower compartment).
