Using the CAL200 Calibrator
This chapter describes how to operate the CAL200
calibrator.
Installing the Battery
The CAL200 uses a nine-volt battery and it is recommended
that you use an alkaline battery to extend the running time of
your calibrator. The
C AL200 will run for approximately 100
hours on one nine-volt battery when using the 114 dB output
level. This will give you nearly 4200 calibrations.
Follow the steps below to install the battery:
Step 1
Slide the battery door on the lower section of the
back panel up to remove it.
Step 2 Gently pull the battery connector clip sufficiently
outside the interior to permit it to be snapped onto the
battery terminals.
Step 3
Tuck the battery, with the battery connector clip
attached, into the battery compartment
Step 4 Slide the battery door back into place, pressing
until the tab snaps the door securely shut.
Microphone Calibration
The CAL200 provides a nominal tone of 1 kHz, which
requires no weighting corrections when used with sound
level meters utilizing A, B, C or Z (Flat) frequency
weighting.
