6-3-1. Initial Set Up
Connect power to recorder and DC power supply.
Connect DVM in paralle with DC output.
6-3-2. Getting Information From Recorder
1. Touch top left key in corner (Logged Out or Operator).
2. Touch Logged Out next to User or User I.D
3. Select Engineer from the drop down menu.
4. Touch box next to Password
5. Touch Numeric tab
6. Touch 1 then 0.
7. Touch Ok.
8. Touch key in bottom right corner (to access Root Menu).
9. Touch Operator.
10. Touch Network.
11. Touch Address from the drop down menu.
12. Enter the Instrument number in the Certificate.
13. Enter the MAC address in the Certificate.
6-3-3. Set Up Recorder For Verification
1. Touch key in bottom right corner (to access Root Menu).
2. Touch home (to display trend graph).
3. Touch bottom left key in corner (to display channels TC1 − TC6).
6-3-4. Calibration Verification
1. Connect voltage source to the RC9 14 − pin connector on the rear of the Recorder. Red lead to pin 1 and black to pin 5.
2. Set voltage source as close as possible to 2.787 Volts DC (must be set to read to 3 decimal positions) using your Precision DVM in parallel to
measure output.
The voltage to temperature caculation is:
(DC Volts In x 155) − 50 =
°
F
(DC Volts In x 86.1) − 45.4 = ° C
3. Enter the achieved voltage below “Voltage In DC” in the Certificate.
4. Verify a TC1 display value of 382.0 (
±
5)
°
F or 194.5 (
±
3)
°
C.
5. Repeat steps 1. − 4. for TC2 – TC6 input jacks. The associated temperature will appear.
1. For TC2 move red voltage source lead to RC9 pin 2.
2. For TC3 move red voltage source lead to RC9 pin 3.
3. For TC4 move red voltage source lead to RC9 pin 4.
4. For TC5 move red voltage source lead to RC9 pin 6.
5. For TC6 move red voltage source lead to RC9 pin 7.
6. Enter Recorder values into Certificate.
7. Repeat steps 1. − 6. with voltage source set as close as possible to 6.013 Volts DC. Verify a display value of 882.0 (
±
5)
°
F or 472.2 (
±
3)
°
C.
8. Repeat steps 1. − 6. with voltage source set as close as possible to 9.239 Volts DC. Verify a display value of 1382.0 ( ± 5) ° F or 750.0 ( ± 3) ° C
6-3-5. Finishing Procedure
1. Disconnect power for recorder.
2. Remove calibrated voltage source.
3. Complete calibration label & place it on unit directly above TC1 display.
I.D. No. (recorder serial number)
By (your initials) Date (today’s date)
Due (date 1 year from today)
4. Print a copy of the certificate to send with the Recorder.
5. If entering data in a spreadsheet, save data.
