To carry, use both hands to lift the device carefully by the converterhousing. If necessary, use lifting gear.When handling the BM 702, avoid hard blows, jolts, impact, etc.When storing the "Wave-Stick" version, make sure that the device is not placed on its side on the PTFE antenna,as this may cause the rod to bend.

However, aparticularly convenient form of parameter setting is offered by the PC program PC-CAT (special accessories, seeabove).→ (cursor key) - selects the configuration menu,- branches the menu to the next lower level,- shifts the cursor* to the next column on the right.↑ resp. ↓ (select key) - branches the menu to the next digit on the same level,- changes the content (digit, text character) at the cursor* position.↵ (ENTER key) - branches the menu to the next higher level,- stores newly entered parameters,- executes displayed functions,- selects special functions (e.g. error memory, see Sect. 5).* The cursor position is signalled by flashing of the character at the appropriate place.Meaning of status markers (only for version with local display)The 6 markers θ x below the local display only show information about the status of measurement and are no error displays!θ1: No current measured value: The device is searching for a new value. If thesearch for a plausible level fails for a certain time, "SIGNAL DOWN" appears aserror display.θ 2: Signal too strong: Mean of reflected microwaves is very high. Gain is automa-tically stepped down.θ 3: Poor spectrum: Brief showing of this marker has no significance. If permanentlyon, this may result in uncertain (incorrect) measured values or the error message"NO M.VALUE".θ 4: No measured value as yet: Evaluable measured values not available after thedevice has been started up. Measured value automatically set to the level of thetank bottom. This marker disappears when the first valid measured value isobtained.θ 5: Tank bottom: In tanks with dished bottom, for example, the measuring signal can"disappear" if measurements are carried out near the bottom. The measured valueis then automatically set to the level of the tank bottom.θ 6: Measurement frozen: Device is in the block distance detection (see below).

FCC Application for Krohne America, Inc. ••FCC ID: JH5BM702 •• Report No. EA0897-1User’s Manual________________________________________________________ 6-Oct-00Page 15 of 25Explanatory notesTank heightThe tank height (Fct. 3.1.1) for the BM 702 is defined as the distance between the top edge of the tankconnecting flange and the bottom reference point. The bottom reference point is that “point“ in the tank on whichthe microwaves of the BM 702 hit and from which they are reflected. This may be the tank bottom (symmetricaltank with flat bottom) or the non-horizontal part of the bottom (e.g. tank with dished bottom) or an additionallyfitted plate. The BM 702 cannot measure below this point (“sump“ in the tank).Note: When the tank is completely empty and the tank bottom provides good reflections (flat, not dishedbottom!), the tank height can also be automatically determined with the aid of Function Fct. 3.5.1 AUTOTANKH. Before confirming, check carefully that the proposed tank height is plausible!Block distanceThe “block distance“ function (Fct. 3.1.2) defines a zone below the top reference point in which measurementsare not meant to take place. The value should be at least 10 - 20 cm greater than the length of antenna+antennaextension, or at least 20 cm in the case of the Wave-Stick.Signals within the block distance are suppressed; a rise in the tank filling above this limit (response threshold)will lead to a measuring result corresponding to a distance = block distance, when Fct. 3.5.6 BD-DETECT. isswitched on.Scaling of the current outputThe scaling of the current output (Fct. 3.3.3: level 1 = 4 mA ; Fct. 3.3.4: level 2 = 20 mA) should if possible liewithin the measuring range (between bottom reference point and response threshold).By pressing the two upper keys (→ and ↑) or the two lower keys (↵ and ↓) at the same time, the 0% setting (= 4mA) or 100% setting (= 20 mA) can be programmed according to the actual level (see page 9). ++++++++++++++++++++++++++++++++Sumpnonmeasurablezonetank height (Fct. 3.1.1)Fct. 3.1.4upper reference point(top edge of tank connecting flange)block distance (Fct. 3.1.2)responsecurrent output20mAmax(Fct. 3.3.4)4min(Fct. 3.3.3)lower reference point(tank bottom / datum point)Fct. 3.1.5thresholdmeasuringmA[e.g.: 5.30 m][e.g.: 0][e.g.: 0][e.g.: 0.6 m][e.g.: 0.4 m][e.g.: 4.0 m]range

Forrecording, the tank should be completely empty and all moving parts (e.g. agitators) switched on. If major inter-ference through internals is not expected, recording of the empty-tank spectrum can also be dispensed with, sincethe factory has already carried out and stored a partial empty spectrum of the flange system.Empty-tank spectrum recording via displayAfter selecting menu item Fct. 3.5.2, press key →. The display then shows whether the empty spectrum iscurrently ON or OFF. Then press the ↵ key if no change is to be made, or use the ↑ key to choose between thefollowing options:• ON: the empty-tank spectrum is (again) switched on and taken into account for measurements.• OFF: the empty-tank spectrum is not taken into account for measurements, but remains stored in theBM 702 and can be switched on again at a later date.• RECORD: the existing empty-tank spectrum is to be deleted and a new one recorded.After selecting "RECORD": if other parameters had previously been changed, the query "ACCEPT YES" is firstmade as to whether they are to be stored. In this case, confirm by pressing ↵. To record, use the ↑ key to selectone of the following options:• MAX. VALUES: (only maximum values are taken into account when the empty-tank spectrum isrecorded; useful e.g. with “difficult“ agitators).• AVERAGE: (values are averaged; this setting can be used for most applications).After selecting with the ↑ key, press the ↵ key to select TOTAL or the ↑ key to select PARTIAL.• When TOTAL is selected, the empty-tank spectrum is recorded over the entire range (tank height).• If the tank has not been fully drained, the empty-tank spectrum can also be recorded up to a certaindistance, in which case the menu item PARTIAL should be selected. When this has been selected, a querytakes place by way of the ↵ key concerning the distance value up to which the empty-tank spectrum is tobe recorded. The tank area below the current filling level is then excluded from the empty-tank recording.It is recommended to maintain a safety distance of 20 to 30 cm from the actual product distance.Subsequently press key ↵ to start recording the empty-tank spectrum. The display starts with “200“ and countsdown to “0“. The sign WAIT... is shown in the display. READY appears after approx. 1-3 minutes. Then presskey ↵ five times to store the recorded empty-tank spectrum, which is taken into account for measurements.Empty-tank spectrum recording via PC-CATConnect the BM 702 and press in the display mode of PC-CAT the key combination Ctrl-L. The type of empty-tank spectrum can be selected by one of the following keys:1: Max.Values 4: Max. Partial A: Break2: Average 5: Avg. PartialTank bottom tracing mode (FTB)The BM 702 includes an additional function for measuring reliably low levels in tanks with flat bottom andpoorly reflecting products (low dielectric constant). This tank bottom tracing system (abbreviated FTB) isactivated in the vicinity of the tank bottom (max. 20% level). Given higher levels, the normal measuring methodis used (reflection from the product surface).If the measurement jumps to the correct level only after filling above a certain level (approx. 0.3-1.0 m), you canactivate the FTB function Fct. 3.5.7 „PARTIAL“. The relative permittivity εr of the tank product must be set inFct. 3.5.8. If it is not known, enter the figure of 2.0. Since the exact position of the tank bottom must be knownfor this process, it is advisable when using the FTB to determine the tank height automatically with an emptytank, using Fct. 3.5.1.Conversion table/Volume table

Press the keystroke combination ↵ ↑ → → to get into the error list. You canpage through the list with key → , and acknowledge the errors at the end - if required - by "QUIT YES". Presskey ↵ twice to return to the measuring mode.Fatal errors (FATAL ERROR), that are detected when the device is started up, render operation of the BM 702impossible.
