Description
MODEL 4024 AND 4024B INJECTION UNIT The Model 4024 is a switch mode voltage source that is used with the Model 4023 Coupling Transformer to produce a high current and low voltage, or high voltage and low current, into an earth loop. The current from the Model 4023 is coupled into the earth loop being investigated.
Frequencies from 45Hz to 65Hz can be generated and the voltage drops around the earth loop are measured with the Model 4025D frequency selective multimeter.
In most cases the operator will try to inject the maximum current into the earth loop being tested since that gives maximum signal for the Model 4025D. For that reason the 4023 has tap settings for earth loop impedances from 0.5 Ohms to 40 Ohms which covers most test situations.
Operation: Front lcd screen plus push buttons to operate.
Operating temperature range: 0 °C … +35 °C Nominal temperature range: 18 °C … +28 °C Storage temperature range: -30 °C … +60 °C
Measurements: 29L x 37h x 28 W
