10-1 MAIN MENUBelow is a block diagram showing the basic menu program. Specific menu breakdownsare described on the following pages. The middle button is used as the enter key.This will move you through the program. The buttons allow you to view andchange variables to the program. Please note, to eliminate changes made, simplydisconnect power before you come to the PWRD YES/NO prompt.ENTER PSWDFigure 20This PortionNot ApplicableIf Password Is Off000 DISPLAYEDTO PASSWORD028 PASSWORD (028 is Universal Password)MENUSNSRJ K T....PRESENT INPUT TYPEor TO SCROLL THROUGH INPUTTYPESDPorRETURN WHENAT DESIRED INPUTTO CHANGE DECIMALUNITorTO CHANGE F / CRLY 1orYES / NO IF YES, SEE FIGURE 21RLY 2orIF NOYES / NO IF YES, SEE FIGURE 21CALIF NOIF CALIBRATING, SEE FIGURE 24PWRDorYES / NO IF YES, SEE FIGURE 23WAIT.V3.1.PRESENTDISPLAYPage 10IF NO

Press the ENTERbutton. MAMP should appear on the display. If not, press thedown button until MAMP is displayed. Press the ENTERbutton.Select proper resolution for the decimal point by pressing thedown button. When proper resolution has been selectedpress the ENTER button.Select proper scale indication by pressing the down button.If °F or °C is not desired, select OFF. Press the ENTER button.(Note: If OFF was selected, scale indication stickers havebeen supplied for the front display)Now that ZERO appears, press the down or up button, thenselect the desired display reading.Once the display reading has been established, connect a4mA source to the input of the meter. Refer to Figure 16 forproper connections. Press the ENTER button. Wait untilSPAN appears.Now that SPAN appears, press the down or up button, thenselect the desired display reading.Once the display reading has been established, connect a20mA source to the input of the meter. Refer to Figure 16 forproper connection. Press the ENTER button, WAIT until UNDRappears.Now that UNDR appears, press the down or up button, thenselect the desired display reading for the under indication.Press the ENTER button.Now that OVER appears, press the down or up button, thenselect the desired display reading for the over indication.Press the ENTER button. Calibration is now complete.Refer to 4 - 20mA menu on page 12 for the above steps (fig. 22)Page 13

15-1 THERMOCOUPLE CALIBRATION PROCEDURE= UP = ENTER = DOWN{Step 1}Power panel meter for at least 30 minutes.{Step 2}{Step 3}Enter menu program, go to the CAL mode. Press the downbutton and hold for approximately 1.5 seconds until the meterreads SHRT, then release the button. Failure to hold the buttonfor 1.5 seconds will terminate the calibration process.Install jumpers between terminals 5, 6, and 7 using copperwire. Press and release the enter button. Wait until 50mVappears. Disconnect jumpers.56JUMPER7Figure 25{Step 4}Now that 50mV appears, connect the leads from the 50mVsource to the meter using terminals 5 and 6, remembering thatterminal 5 is negative. Set the voltage supply for 50.040mV,then press and release the enter button. This simulates athermocouple input. Wait until 100 ohm appears. Disconnectsupply.{Step 5}Press the down button to skip 100 ohm input.{Step 6}Now that CJC appears, place the thermometer across theterminal strip and do not remove until the temperature stabilizes.The reading from the thermometer is going to be the newCJC temperature. Press and release the enter button. Use theup or down button to set the value, then press the enter buttonthree times until V3.1 appears. Calibration is now complete.Figure 26CJC COMPENSATIONNote: If calibration is off due to the CJC, refer to CJC Calibration on page 17Page 15

16-1 RTD CALIBRATION PROCEDURES= UP = ENTER = DOWN{Step 1}Power panel meter for at least 30 minutes.{Step 2}Enter menu program, go to the CAL mode. Press the downbutton and hold for approximately 1.5 seconds until the meterreads SHRT, then release the button. Failure to hold the buttonfor 1.5 seconds will terminate the calibration process.{Step 3}Install jumpers between terminals 5, 6, and 7 using copperwire. Press and release the enter button. Wait until 50mVappears. Disconnect jumpers.56JUMPER7Figure 27{Step 4}Press the down button to skip 50mV input.{Step 5}Now that 100 ohm appears, install jumper between terminals6 and 7, and insert the 100W resistor into terminals 5 and 6.Then press and release the enter button. This simulates a 3wire RTD. Wait until CJC appears.
