Grid dip meter millen 90662-a, all 11 coils, calibrated
Very clean Millen 90662-A Grid Dip Meter with all 11 coils offering continuous coverage from 220 KHz through 300 MHz. Included in the complete package are:
r The standard seven HF/VHF Coils plus the hard-to-find four Low Frequency coils.
r Original Custom Factory Calibration Chart for the LF coils for this particular Serial Number.
r Original Instruction Booklet.
r Loop-to-Loop (coupling) test cable.
This grid dipper, the coils and the storage/carrying case are in excellent shape with expected small scratches etc. on the case. The grid-dipper itself looks very clean as does its dial; however, there is one small distortion "dimple" in the paper roller dial at the high frequency top end. See the pictures, below.
On 4/23 I tested this unit against an accurate frequency counter and found that this Model 90662-A has maintained its calibration very well. Here is a list of the readings, taken after a 10-minute warm-up:
