4 MT2000-0 200-01 Rev f (10-2007 ) DCN0160 1.0 INTRODUCTION Thank you for using the K-TEK MT2000 Guided Wave Radar Tran smitter. The MT2000 has been desi gned for ease of use and to offer extensive configurati on capabilitie s. You are urged to review this manual in its entirety prior to use.
MT2000-0200-1 Rev f (10-2007) DCN0160 5 2. OVERVIEW 2.1 Storage Information If required, storage prior to installation should be indoor s at ambient temperature, not to exceed the followin g: Temperature range: -40 to 150 de grees F. Humidity: 0 to 100% R.
6 MT2000-0 200-01 Rev f (10-2007 ) DCN0160 2.3.1 Direct Reflect Mode (standard) (cont’d) The measurement principle usin g TDR is based on the fact that a dielectric constant discontinuity or g eometric change will yield a negative pulse having certain amplitude belo w the baseline.
MT2000-0200-1 Rev f (10-2007) DCN0160 7 3. INST ALLA TION 3.1 Mounting Requirements IMPORTANT: To obtain the be st re turn s ignal from the product level it is recommended to mount the MT2000 cou- pler directly into the top of the vessel if the vessel material is metal, or into a metal plate if the vessel is non-metallic.
8 MT2000-0 200-01 Rev f (10-2007 ) DCN0160 3.2 Shortening of Probe The MT2000 single probe can be cut to length prior to in stallation. The MT2000 default factory configuration pro- vides a measurement in engineering units with a zero refe re nced to the bottom of the s ensing probe.
MT2000-0200-1 Rev f (10-2007) DCN0160 9 Rods: • 1/4”rod 5 ft. max, minimum 3” Dia. Stilling well if provided with stilling well. • 1/2” rod 10 ft. max, minimum 3” Dia. St illing well if provided with stilling well. • In 2” pipe: 5ft. Max 1/4” or 1/2” rod.

MT2000-0200-1 Rev f (10-2007) DCN0160 17 4.5.5 Bench Calibration of the 4mA & 20mA Points: After the transmitter is configured correctly, a manual ben ch calibration of the 4mA and 20mA points using han ds or targets, can be done as follows. Note: The following applies to single or dual Ro d and Cable probes only.
18 MT2000-0 200-01 Rev f (10-2007 ) DCN0160 4.5.7 Reversing The Output Action Using Actual Level Input • Adjust the level to 50% ( + or - 10% ). • Enter the calibration mode by pressing the UP & DOWN buttons together for 1 se cond and press the DOWN button for 1 second to set the output at 4.
MT2000-0200-1 Rev f (10-2007) DCN0160 19 5. TROUBLESHOOTING INFORMA TION Use a milliamp (mA) meter to measure the output current. When power is applied the output will go to 4.00 mA for at least one (1) second and then to either the me asured level or an alarm condi tion output.
