Battery Pack Battery Lid
• Using your fingers only, loosen the four captive screws on the battery lid until they turn freely.
NOTE: If the screws are too tight to remove by hand, it is permissible to use a slotted screwdriver to
loosen them.
CAUTION: The battery lid screws are captive. Do NOT continue to turn them after the
battery lid can be removed.
• Grasp the handle on the battery lid and pull straight up to remove it, exposing the battery compartment
as shown in the picture above right. Set the lid aside for later reassembly.
• Locate the hexagonal battery pack that is stored in the battery compartment and is shown in the picture
above right. Note that there is a cable attached to the battery pack with a 2-wire connector.
• Note that there is also a cable coming out of the side of the battery compartment that also has a mating
2-wire connector.
• Connect the two 2-wire connectors together to power the instrument from the battery pack.
• Replace the battery lid and tighten the four screws using your fingers only.
IMPORTANT: If the two battery cables are connected, then the batteries are slowly being
discharged even if the instrument is not being used actively. Therefore, for periods of inactivity
lasting more than a few hours, YSI recommends that you remove the battery lid and disconnect the
two connectors in order to maximize the lifetime of your battery pack.
3.3.2 USING THE MODEL 9689 POWER SUPPLY
Although the Model 9600 has internal batteries, using the optional Model 9689 power supply for laboratory
studies and for instrument calibration and set-up is often convenient and extends battery life. The 9689 will
automatically convert line voltages of 90 to 264 VAC to 12 VDC and allows for the use of line input cords
from most countries world-wide. The Model 9689 is supplied with an American/Canadian cord.
To use the 9689, attach the four-pin connector from the power supply to the mating connector on the 6067B
cable or the 6095B adapter when using a field cable. Twist the connectors together and then simply plug
the power cord into the appropriate AC outlet. The 9600 is equipped with reverse voltage protection so
