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 CAL200 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.
