The Yokogawa CA450 Process Multimeter is a portable test instrument to combine a digital RMS multimeter and a loop calibrator to give process technicians the same functionality in one tool. The Yokogawa CA450 provides 24-Volt loop power, reducing the need for carrying a separate power supply when performing transmitter testing. And with its built-in, selectable 250-Ohm Hart resistor, it also eliminates the need for a separate resistor. Process technicians can now do the same job while carrying less equipment.

Laboratory-grade accuracy ±0.03 to ±0.05% Quick readout without error Excellent long-term stability: The resistance elements are made of selected manganin wire, stabilized by both artificial and natural aging after being wound. Perfect guard system Stable measurement: The dial switches offer low contact resistance and little change due to aging, giving stable operation. Inner/outer contact type plugs are used for changing the multiplication factor, assuring little change in the resistance due to reinsertion of plugs. Built-in standard resistors Bar resistor measurement

Model 2768 is a Precision bridge used for the exact determination of resistance in the 100 MΩ to the 110MΩ Range with an accuracy of 0.01 to 0.05%. Since this instrument includes a high-sensitivity transistorized galvanometer and bridge power source, no auxiliary device is required. Superior resistor aliment Minimized contact resistance Guarding and shieldingMaterials of high insulation resistance and low absorption are employed. Guard circuits are provided to insure stable operation even In highly humid atmospheres. The instrument is housed in a {grey} metal case to assure -to operator of excellent shielding. Heat-insulated pushbutton keysIf the operator's body temperature were carried to the galvanometer sensitivity control keys, a temperature difference would arise at the contact point and produce thermal EMF resulting in measurement error. To eliminate this effect, the pushbutton keys for the galvanometer sensitivity control are heat-insulated with phenol resin.
