Introduction The Stik Thermometer (the Product) is a precision digital thermometer that can be used as an alternative to mercury liquid-in-glass (LIG) thermometers. It can also be used as a reference standard for other types of digital or analog thermometers. Because of its intrinsically safe certification, it can be used in many of the same hazardous locations as analog thermometers. For complete usage instructions, see the 1551A Ex/1552A Ex Users Manual.
1551A Ex/1552A Ex Calibration Manual Safety Information A Warning identifies conditions and actions that pose hazard(s) to the user. A Caution identifies conditions and procedures that could cause Product damage, equipment under test damage, or permanent loss of data. Symbols used on the Product and in this manual are explained in Table 1.
Stik Thermometer Safety Information If the Product overheats or is exposed to sudden physical shock, examine it for damage that can cause a safety risk. If possible, compare the displayed temperature to a known reference before Product use. If not sure, send the Product to Fluke Corporation. Refer to “How to Contact Fluke”. Substitution of components will impair suitability for hazardous locations.
1551A Ex/1552A Ex Calibration Manual Approvals The Product meets the above requirements using: EN 60079-0:2006 ELECTRICAL APPARATUS FOR EXPLOSIVE GAS ATMOSPHERES -- PART 0: GENERAL REQUIREMENTS (IEC 60079-0:2004 (MOD)) EN 60079-11:2007 EXPLOSIVE ATMOSPHERES -- PART 11: EQUIPMENT PROTECTION BY INTRINSIC SAFETY "I" (IEC 60079-11:2006 (EQV) + CORRIGENDUM DEC. 2006 (EQV)) Manufactured by Fluke Corporation: Fluke Corporation P.O.

1551A Ex/1552A Ex Calibration Manual Recommended Equipment The equipment listed in Table 2 will satisfy the calibration requirements: Table 2.
Stik Thermometer Calibration Record as-found Calibration Parameters Before any adjustments are made, the present values of the Product calibration parameters should be recorded. Connect the serial cable between the computer and the Product. The commands used to read the values of the calibration parameters are given in Table 3. Commands must be terminated with a carriage return character. Table 3 may also be used to record the values of the calibration parameters. Table 3.
1551A Ex/1552A Ex Calibration Manual At each calibration point the measurement error may be calculated by subtracting the reference thermometer temperature from the 1551A Ex/1552A Ex temperature. The temperatures and measurement errors may be recorded in Table 5. Table 5.
Stik Thermometer Calibration Adjustment at the Zero Calibration Point The next adjustment is made for the middle of the temperature range of the Product. Set the bath temperature to the Zero Adjustment Temperature given in Table 7. Make sure the temperatures of the bath, reference thermometer, and the Product are settled and stable before proceeding. Table 7.
1551A Ex/1552A Ex Calibration Manual The command will set the value of the CAL:USER:TEMP3 parameter to the given temperature and automatically adjust the CAL:USER:ADJ3 parameter to cause the Product to measure the given temperature accurately. The adjustment made here will not affect the measurements at the other Adjustment temperatures.
static awareness A Message From Fluke Corporation Some semiconductors and custom IC's can be damaged by electrostatic discharge during handling. This notice explains how you can minimize the chances of destroying such devices by: 1. Knowing that there is a problem. 2. Learning the guidelines for handling them. 3. Using the procedures, packaging, and bench techniques that are recommended. The following practices should be followed to minimize damage to S.S. (static sensitive) devices. 1.
5. USE STATIC SHIELDING CONTAINERS FOR HANDLING AND TRANSPORT. 8. WHEN REMOVING PLUG-IN ASSEMBLIES HANDLE ONLY BY NON-CONDUCTIVE EDGES AND NEVER TOUCH OPEN EDGE CONNECTOR EXCEPT AT STATIC-FREE WORK STATION. PLACING SHORTING STRIPS ON EDGE CONNECTOR HELPS PROTECT INSTALLED S.S. DEVICES. 6. DO NOT SLIDE S.S. DEVICES OVER ANY SURFACE. 9. HANDLE S.S. DEVICES ONLY AT A STATIC-FREE WORK STATION. 10. ONLY ANTI-STATIC TYPE SOLDERSUCKERS SHOULD BE USED. 11. ONLY GROUNDED-TIP SOLDERING IRONS SHOULD BE USED. 7.
Stik Thermometer Maintenance Maintenance Clean the Product WCaution To prevent possible damage to the product or to equipment under test, do not use abrasive cleaners. They will damage the case. To clean the Product, use a cloth with a mild cleaning solution. Battery Replacement XWWarning To prevent possible explosion, fire, or personal injury: • Change the batteries only in areas that are not Exhazardous. • Replace the batteries when the low battery indicator shows to prevent incorrect measurements.
1551A Ex/1552A Ex Calibration Manual To change the batteries, see Figure 1: 1. Use a flat-blade screwdriver to remove the battery door screw. 2. Remove the battery door to access the three AAA batteries. 3. Replace only with approved AAA batteries listed in this document. See Table 11. Any substitution voids the Product safety rating. 4. Make sure the battery polarity is correct. 5. Replace the battery door and install the screw. gjo003.eps Figure 1. Battery Replacement Table 11.
