######################################################################## INT5 evaluation checks for any errors in manual and glitches in meter. ######################################################################## Manual is available at https://ez-docs.net Prepared 16 April 2021 - G. Laming =============================================================== Preparation: =========== 1. Connect power. 2. Connect pushbuttons to all logic inputs. 3. Do all tests with meter in case, front lens fitted. Inventory Report ================ Do an inventory report to see which options are fitted to your meter. Active digits ============= The meter can be set for 6 digits or 4 digits display, either to limit resolution, or for when installed in 6 digit or 4 digit Fusion5 displays. The menus and prompts have been designed to be identical for both. This is a simple test to ensure you can access the Active Digits part of the menu and that it has the correct effect. 1. Set to 4 digit display 2. Set to 6 digit display - leave in 6 digit for the following tests. We will later repeat in 4 digit mode. Boot Modes ========== 1. Set Boot 1 and check it responds as described. 2. Set Boot 2 and check it responds as described. 3. Set Boot 3 and check it responds as described. 4. Set Boot 4 and check it responds as described. Clock ===== 1. Set meter for clock mode HH:MM:SS with a green display 2. Set AL1 as HI alarm, to go off in 1 minute with RED display. 3. Set serial data port 1 output to mode C1 at 9600 baud and confirm that the time data is coming out correctly 4. Set serial data port 2 output to mode C1 at 19200 baud and confirm that the time data is coming out correctly 5. Set mode to dd.mm.YY and confirm that the date displays correctly and data output matches that. 6. Set mode to HH:MM and confirm that the date displays correctly and data output matches that. 7. Try setting the clock time to exactly match the reference clock on the manual's clock page. 8. Set the mode to Day.C which is days counter. Set a preset value of 55 days. Brightness ========== 1. Try adjusting brightness to each of 9 levels. Does the display repond as expected? Power Frequency =============== 1. Set meter for power frequency display mode in colour red 2. Set AL1 as an in-band alarm with low setpoint of 49.990 and high setpoint of 50.010 green 3. Does the display correlate exactly with the national grid value you can see at http://mainsfrequency.uk/fm-fullscreen ? 4. View the Min and Max values of power frequency, then reset them and view again. 5. Does the power frequency appear correctly in the serial data output stream? Totaliser ========= 1. Set the meter to Pulse/Total mode with green display. 2. Set for 3 pulses = 1 count. 3. Set debounce to 500 milliseconds 4. Check that the meter counts correctly for slow pulse rates of around 1 per second and that you can reset to 0. 5. Check that the counter inhibits fast pulse rates of more than 2 per second. 6. Change debounce to 10 milliseconds. 7. Check that the counter now responds correctly to pulse rate of over 2 per second. 8. Check that the count value is being sent correctly by the serial data ports. 9. Set AL1 to be HI at 5 counts, amber. Does it function as expected? 10. Set AL2 to be HI at 10 counts, red. Does it function as expected? 11. Set analogue output to 4-20mA, setLo = 0, Set Hi = 20. Does it output as expected? 12. Set analogue output to 0-10V, setLo = 0, Set Hi = 20. Does it output as expected? Elapsed Timer ============= 1. Set the Elapsed timer to show time elapsed in SSS.t format. Red display. Up count, no preset. 2. Monitor elapsed time on serial output data port - does it read correctly? 2. Try Start/Stop/Reset - does the timer count correctly? 3. Set the Elapsed timer to show time elapsed in MM:SS format. Red display. Up count, no preset. 4. Try Start/Stop/Reset - does the timer count correctly? 5. Now set to Down count, with a preset of 01:00. Neg. N so it stops at 0 6. Set AL1 = Lo, 00:01 Green. Should count down from 01:00 to 0 in red, and on reaching 00:00 stop and turn green Rate Meter ========== 1. Set the rate meter to display bottles per minute, with 1 pulse per bottle, with an averaging time of 1 minute. Amber display. 2. Set debounce to 20 milliseconds. 3. Does the display respond correctly? Ambient Temperature monitor =========================== 1. Set the mode to CJ.t Green display 2. Does the display show room temperature? 3.

Does the serial data respond correctly? mV Shunt meter ============== 1. Set the meter to Shunt mode and connect your DC calibrator to the meter. 2. Calibrate Direct Cal for 0-60mV = 0-1000.0 A 3. Does the meter read correctly through the range? How about if you go negative? 4. Try adding some filtering to see how the meter responds to step changes. Try Fil 1.0. Does the meter settle cleanly? No jitter? 5. Does the serial data output reflect the reading correctly? 6. Now calibrate Theoretical mode 0-50mV = 0-250A 7. Does the meter read correctly through the range? How about if you go negative? Try Fil 5.0. Does the meter settle cleanly? No jitter? 8. Try setting the Count by to 5 - does the meter respond correctly, both positive and negative? 9.

Check 12mA for 80000 , 8mA for 40000, 16mA for 120000 4. Does the serial data output correspond with the display value? 5. Now connect a 24V DC power supply to the input instead of 4-20mA - try to burn out the input resistors. Leave for 1 minute. 6. Does the diagnostic message make sense? 7. Now re-connect 4-20mA and try 4mA, 8mA, 12mA, 16mA and 20mA. Is the calibration all OK as before? No burned resistors? 8.

Change resistance gradually (around 109 Ohms) so it goes through each temperature. Do the alarms respond as expected? Resistance Meter ================ 1. Try setting each of the available resistance ranges on the meter. 2. Monitor serial data output, does it correspond to the resistance? 3. Set the range to 100 Ohms and connect a 51R MRS25 to the display, using 4 wire connection, around 50 cm wire length. Note the reading on display. 4. Check cable resistance compensation and warning alarm feature, as follows... Fit the resistance decade box in series with the lead going to terminal 2. Set to 0 Ohms. Is the reading the same? Raise to 5 Ohms - is the reading the same? Keep raising - does the X annunciator illuminate to warn you that your cable resistance has changed? At what cable resistance does the reading start to corrupt? Now, fit the resistance decade box in series with the lead going to terminal 7 instead of 2. Set to 0 Ohms. Is the reading the same? Raise to 5 Ohms - is the reading the same? Keep raising - does the X annunciator illuminate to warn you that your cable resistance has changed? At what cable resistance does the reading start to corrupt? Load Cell Meter =============== 1. Connect the meter to a load cell and set for Direct calibration. 2. Calibrate with known weights, which do not exceed the capacity of the load cell. 3. Check serial data output corresponds with the reading 4. Set Fi1.0 Is display stable if you knock the table supporting the load cell? 5. Check cable resistance compensation and warning alarm feature, as follows... Place your calibration load on the loadcell and note the reading. Fit the resistance decade box in series with the excitation lead going to terminal 2. Set to 0 Ohms. Is the reading the same? Raise to 5 Ohms - is the reading the same? Keep raising - does the X annunciator illuminate to warn you that your cable resistance has changed? At what cable resistance does the reading start to corrupt? Repeat, but with the decade box in series with the lead going to terminal 7 (Excitation +) Try with the decade box in the wire going to terminal 4 (Sig - ) and then Terminal 5 (Sig +) The signal wires will not report that cable resistance has changed, but the display should remain stable as resistance changes from 0 to 20 Ohms approx.
