BRUEL & KJAER 2230 User Manual

3. OPERATION
3.1. INTRODUCTION
This Instruction Manual describes the use of the Precision Integrating Sound Level
Meter Type 2230. However, more general considerations on sound measurement tech-
niques must be taken in account, and these are given in the accompanying booklet
"Measuring Sound". To obtain valid results it is also important that the measurements
are carried out according to the relevant national or international standards.
3.2. BATTERY INSTALLATION
12
The
Type 2230 is powered by 4 batteries 1,5 V, IEC Type LR 6. New alkaline batteries
(B & K No. QB 0013) will provide approximately 8 hours of continuous operation, and
when the
"BAT" symbol flashes in the display approximately half an hour of operation
is left. When a non-resettable "i" is displayed at the same time as "BAT", new batte-
ries must be fitted.
To install new batteries slide the lock downwards and pull out the battery drawer, see
Fig.3.1.
Remove the depleted batteries and place new batteries with polarities as
shown inside the battery drawer. Put back the battery drawer.
