Product components<br />
Make sure that all the components that follow have been received. If any items are missing or<br />
damaged, contact the manufacturer or a sales representative immediately.<br />

• Batteries, 6 V alkaline (4x)<br />
Apply power to the <strong>Logger</strong><br />
Install the batteries<br />
W A R N I N G<br />
Explosion hazard. Incorrect battery installation can cause the release of explosive gases. Be sure that<br />
the batteries are of the same approved chemical type and are inserted in the correct orientation. Do not<br />
mix new and used batteries.<br />
W A R N I N G<br />
Fire hazard. Battery substitution is not permitted. Use only alkaline batteries.<br />
N O T I C E<br />
Do not over-tighten the cover. Tighten until the cover just touches the O-ring, then tighten one-quarter to one-half<br />
turn maximum from O-ring contact. Keep the O-ring lubricated with silicone grease.<br />
The instrument can use two or four 6 V batteries for power. Use two batteries for short-term use or<br />
four batteries for long-term use (for battery life, refer to Specifications on page 3). When only two<br />
batteries are used, put both batteries on the same side of the compartment (A-A or B-B). Refer to the<br />
illustrated steps that follow.<br />
Changes in temperature and pressure can cause the battery compartment cover to be difficult to<br />
remove by hand. If this occurs, a tool can be used to remove the cover (Figure 3).<br />
