The Type 358 is an absorption type wavemeter covering the four overlapping bands.  It has an frequency accuracy of 1% and uses an incandescent lamp as a resonance indicator.  The lamp is in a special socket that closes the connection when the lamp is removed if not needed. A Type [[247]] gear driven condenser is used inside the meter. Each wavemeter is supplied with a calibration chart produced with settings accurate for that particular meter.
