Electronics "What an excellent idea the remote display multimeter is! This would be an ideal tool for working in the back of electronic equipment racks. When working on rack-mounted equipment, you often have to attach probes in awkward locations in the rack, and trying to read a meter inside the rack, sometimes sideways or upside-down, is difficult at best - especially when you are holding the leads with both hands! The ability to place the display in a convenient location and then have your hands free for the probes would be a terrific capability, as good as an additional person." D.E., Florida "I am a broadcast engineer. I work primarily in radio and most of my work is with transmitters. Troubleshooting transmitters is often a dangerous and time consuming process. Modern transmitters (and of course older ones too) still use vacuum tubes. These tubes are often large and use very high voltages. Everything between 3,000 and 12,000 volts DC. Furthermore these tubes are mounted in enclosures which must be closed when operating. It is often very difficult to diagnose a problem by measuring voltages inside this enclosure. You can't see the meter! And often stringing leads through a door on the enclosure doesn't work because the door won't close all the way. This causes voltage interlocks and air interlocks to be open. The 233 opens up countless opportunities for this kind of troubleshooting. I can hardly wait to get my hands on one and have the ability to remotely look at filament voltages, grid bias voltages, screen voltages and even very high plates voltage using a high voltage probe. What a great invention!" J.B., Oregon "Our engineers have designed automated test racks that look great: all the cables are inside the cabinet and there's only one connection on the front to attach the unit under test. Unfortunately for me, when I have to calibrate the power supplies I often have to be in two places at once; at the back, inside the cabinet where the connections are, and in the front where the controls are. With one of these multimeters I could eliminate the back and forth, and be far more productive." R.S., California 13
