1. 18 Practical Application and Use CAUTION Before connecting any components follow the safely information in the ETS Lindgren Product Information Bulletin included with your shipment System Theory HI 4433 series Broadband RF Probes utilize a microprocessor for intelligent operation and control Their self contained power supply employs a 3 6 VDC NiCd battery which provides up to 20 hours of continuous operation For each axis the probe measures the radio frequency signal level and generates a linearized reading of this measurement A vector addition is performed on these three readings the resultant is transmitted to the readout over glass fiber optic cables Receiver commands to the probe consist of the following e Send reading e Setsleep timer e Read battery e Switch range voltage Read temperature Zero Enable axis Automatic Zero This feature eliminates the need for internal zero adjustment and eliminates the temperature drift problems associated with other instrumentation The automatic continuous zero also allows the operator to use the meter immediately upon power up Also it is not necessary to place the meter in a zero field environment to check its zeroing 19 In addition to the inputs from the three axes HI 4433 series probes utilize a fourth input called the Autozero channel This is a redundant channel identical to the three axis channels except that instead of being dr2. 1 hour e Length 559mm 22 0 in e Probe Diameter 102mm 4 0 in Size e Weight 0 57 kg 20 oz Including electronics housing Probe Mount Ya 20 UNC tapped hole internal thread in base of probe 15 H Field Probes HI 4433 HCH e Ranges 0 1 0 3 1 0 3 0 A m full scale Frequency Response 5 0 MHz to 300 MHz See General Specifications table for additional information HI 4433 LFH LFH Ranges 1 0 3 0 10 0 30 0 A m full scale Frequency Response 0 3 MHz to 30 0 MHz See General Specifications table for additional information 16 HI 4433 CH CH gt Ranges 0 3 1 0 3 0 10 0 A m full scale Frequency Response 5 0 MHz to 300 MHz See General Specifications table for additional information E Field Probe Specifications HI 4433 STE STE Ranges 100 300 1000 3000 V m full scale Frequency Response 0 5 MHz to 5 0 GHz See General Specifications table for additional information 17 HI 4433 GRE GRE Ranges 10 30 100 300 V m full scale Frequency Response 0 5 MHz to 5 0 GHz See General Specifications table for additional information HI 4433 MSE MSE Ranges 30 100 300 1000 V m full scale Frequency Response 0 5 MHz to 5 0 GHz See General Specifications table for additional information
