1. To enable the RapidTrace 1200 to test all metallic cables 4 user selectable impedance settings are provided 25 50 75 and 100 ohms with Vp settings of 1 99 or the equivalent in feet or meters per micro second Faulty cables may be traced using the warble tone feature an oscillating tone is injected into the power or transmission line and by using a commercially available tone tracing probe the suspect line can be identified The RapidTrace 1200 is CE approved and is housed in a ruggedABS enclosure rated to IP54 and is suitable for outside use 5 2 1 RapidTrace 1200 Features RapidTrace 1200 na SCAN LOCK VONAQ RapidTrace 1200 1 2x4mm safety connectors 2 128 x 64 graphics display 3 Cursor left decrease setting 4 Cursor right increase setting 5 Store trace select 6 Scan lock Cursor down 7 Range Return 8 Back Light On Off 9 Power on off 10 Gain Control 2 2 Specifications Ranges Meters Feet Range Selection Accuracy Resolution Sensitivity Velocity Factor Output Pulse Output Impedance Output Pulse Width Scan Rate Memory Caoacity Tone Generator Battery Life Power Supply Power Down Back Lit Display Voltage Protection Operating Temp Storage Temp Dimensions Weight Safety EMC Water Dust Proof 7 15 30 60 120 250 500 1km 2km 3km 6km 23 49 98 197 394 820 1640 3280 6560 9850 19000 Manual range control 1 of selected range2.
