2.0 Introduction
The JOFRA DLC-155, DLC-158, DLC-250 and DLC-700 probes are designed for fast and traceablecalibration and temperature measuring with JOFRARTC-156/157 B/C, JOFRA RTC-158 B/C, JOFRARTC-250 B/C and JOFRA RTC-700 B/C systemsand are ready for use.
Please read this manual carefully before use, toobtain maximum value of your calibration system.
Warning
Read this manual before use.
Do not use in hazardous area.
Handle carefully.

3.0 Functionality
3.1 Functional description
The probes can be used for temperatures in therange :
DLC-155 : -60C to 155C / -76F to 311F
DLC-158 : -60C to 155C / -76F to 311F

5.1 Calibration
Required equipment:
DLC-probe to be calibrated. RTC-calibrator with DLC-input.
An insert with correct size holes for the DLC-probe and the temperature probe.
For calibrating DLC-155, DLC-158 and DLC-250:an AMETEK 127587 temperature probe(recommended) or similar with short measuringzone is required.
For calibrating DLC-700: a STS-200 A 970temperature probe (recommended) or similar isrequired.
Procedure:
1. Place the DLC-probe in the insert and connectthe probe to the DLC-input of the calibrator.
2. Go to the Sensor setup menu.
3. Set Use load compensation to YES. If thereference probe is connected to the REF input,
set Sensor type to External and SET followsTRUE to No. If no reference probe isconnected, set Sensor type to Internal.
4. Enter the DLC-menu.
5. Read the A, B and C-coefficients of the probeand enter the values in the EXCEL spreadsheet
(127588 DLC-155.XLS, 127884 DLC-158.XLS,127885 DLC-250.XLS or 127589 DLC-700.XLS).

The following procedure is repeated for eachtemperature:
1. Set the SET temperature.
2. Place the reference temperature probe in thebottom of the insert.Wait until the temperature have stabilized and theDLC-reading is 0.00C. If the DLC-readingcontinuously shows a positive value at -30C(RTC-156) / -45C (RTC-157) / -22C (RTC-158),increase the SET-temperature in steps of 1C
until the DLC-reading displays 0.00C.

3. Record the temperature of the reference probe inthe excel spreadsheet.
4. Move the reference probe to the upper position
60 mm (RTC-156/157/158/250) or 80 mm (RTC-700).
5. Wait until the temperature have stabilized and theDLC-reading is 0.00C.
6. Record the temperature of the reference probeand the DLC-probe in the excel spreadsheet.
7. Go to next SET-temperature.
After the last STEP is completed:
8. Check that all values in the calculated curve fitare less than the values specified in the table. Ifthis is OK, the new coefficients can be
downloaded using the CON050 software.
