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. XWWarning To prevent possible electrical shock, fire, or personal injury: • Use the Product only as specified, or the protection supplied by the Product can be compromised. • Do not use the Product to measure the temperature of hazardous live components. • Do not open the Product case. If you open the case, the Ex approval is not applicable. • Change the batteries only in areas that are not Ex- hazardous. • Use only specified approved batteries in the Product. Refer to the battery replacement instructions for a list of approved batteries. • Do not use and disable the Product if it is damaged. • Replace the batteries when the low battery indicator shows to prevent incorrect measurements. • Check for proper operation of the Product before taking it into a hazardous area. Should the Product not operate as expected do not take the Product into a hazardous area and return it to the manufacturer for inspection. • The Product is intended for installation only in locations providing adequate protection against the entry of solid foreign objects or water capable of impairing safety. WCaution To prevent possible damage to the Product or to equipment under test: • If the display message changes to "OL," the range limit is exceeded and the Product must immediately be removed from the heat source to prevent damage. • Do not immerse the Probe beyond its maximum immersion depth. This may damage its internal electronics. See "Immersion Depth and Usage" later in this manual. • DO NOT drop or strike the Probe in any way. Mechanical shock damages the Probe internally and affects it calibration. 2
