- 25 -ADDENDUM FOR "METERS" OPTION OF THE TRANSMITTERSFig. 1 - Analog meter adj.Zero adj.ANALOG OUTPUT METERThe analog output meter provides a 90° scale indication. It haseither a 0 to 100 linear scale or a 0 to 10 square root scale.ANALOG OUTPUT METER CALIBRATIONThe calibration of the analog type meter only involves zeroing.Fig. 1 shows the analog output meter and the location of thezero adjustment.The calibration is quite simple using one of the followingmethods:- with the loop unpowered adjust the zero screw to read exactlythe true zero mark on the scale (Fig. 1).- with the transmitter transmitting 4 mA adjust the zero screwto read exactly the live zero of the scale.GENERAL DESCRIPTIONThis option provides three different indications (meters) inside the transmitter housing. The "output meters" can be mounted onthe terminal block (field terminals) side; one is of "analog" type, the second is of "digital" type (LCD, ProMeter) and the third isthe CoMeter. They are operated by the output signal of the transmitter. The meters can be rotated to exactly match the mountingposition of the transmitter . The above mentioned CoMeter (abbreviation of Communication Meter) can be used both as a displayand as a configuration tool for the Safety 2600T.0 1004%8060402020128 16mA Fig. 2 - Cover Internal labelTo install (or to replace) the meter, use the following procedure:1) If the transmitter is part of a control loop, put the loop inmanual.2) Remove the cover on the terminal block side; inside ofwhich is affixed the label shown in Fig. 2.3) Remove the link shown on the label by pushing down at itsleft extremity and then its right . Alternatively it can beremoved on the left side only in preparation for a furtherrefit.4) Plug the meter into the socket. The digital indication metercan rotate, for easy viewing, in 15° steps, 90° degreeclockwise and 255° counterclockwise.Further rotation causes damage to the meter stops or to the"banana" connections and should be avoided. Note thatconsiderable effort must be applied for 15° rotation. Theanalog output meter can also rotate for easy viewing.5) Check that the cover O-ring gasket is properly in place,screw on the extended windowed cover and tighten properly.To remove the meter simply pull it out from the socket and fita replacement following the above procedure.CAUTION - If the meter is removed, ensure that it isreplaced immediately by another one or with the properlink provided. This operation is important for I.S.loop operation.METER INSTALLATION OR REPLACEMENTWARNING - If the transmitter is not certified asIntrinsic Safety type, DO NOT REMOVE ANY COVERin areas classified as "HAZARDOUS LOCATIONS:CAN RESULTS IN HAZARD OF FIRE ANDEXPLOSION". Contact your Safety Dpt. in order toestablish correct installation procedure.
