A Caution identifies conditions and procedures that can cause damage to the Product or the equipment under test. XW Warning To prevent personal injury, use the Product only as specified, or the protection supplied by the Product can be compromised. To prevent possible electrical shock, fire, or personal injury: 2 • Read all safety Information before you use the Product.
Documenting Process Calibrator Symbols • Connect the common test lead before the live test lead and remove the live test lead before the common test lead. • Use only current probes, test leads, and adapters supplied with the Product. • Do not touch the probes to a voltage source when the test leads are connected to the current terminals. • Use only cables with correct voltage ratings. • Do not use test leads if they are damaged.
753/754 Calibration Manual Specifications General Specifications All specifications apply from +18 °C to +28 °C unless stated otherwise. All specifications assume a 5-minute warmup period. Measurement specifications are valid only when Damping is turned on. When damping is turned off, or when the gannunciator is shown, floor specifications are multiplied by 3. Floor specifications are the second part of the specifications.

Documenting Process Calibrator Performance Verification Tests Performance Verification Tests Fluke recommends re-certification each year. To re-certify, do the verification procedure. If test points are out of tolerance, calibrate the Product and then re-verify. Two-year specifications are included if the highest accuracy is not necessary. Use the subsequent tests to make sure that the Product is inside its specification limits.
753/754 Calibration Manual How to Verify For each procedure there is a table of test points and permitted readings. If the result of the test is not in the range shown, the Unit Under Test (UUT) is out of tolerance and must be re-calibrated or repaired if necessary. There are columns for 1 and 2-year specifications wherever the specifications are different. Follow these general instructions for all the tests: • For all tests, operate the UUT on battery power. Make sure the battery is fully charged.

Apply the subsequent requested value as in step 5. Push the Continue softkey. When you record a negative value, always start with ‘-’. XWWarning Some of the voltages required for calibration are dangerous. To avoid injury or death from electric shock, do not touch live conductors during high-voltage calibration.
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.
Documenting Process Calibrator Maintenance Maintenance XWWarning To prevent possible electrical shock, fire, or personal injury: • • • • Have an approved technician repair the Product. Do not operate the Product with covers removed or the case open. Hazardous voltage exposure is possible. Remove the input signals before you clean the Product. Use only specified replacement parts. Battery Replacement Replace the battery when it no longer holds a charge for the rated interval.
753/754 Calibration Manual Calibration Data The date of the last calibration and verification shows on the calibration sticker and on the calibration screen in Setup mode. The CAL. STATUS number on the sticker should always match the Calibration Status number in the calibration screen. Calibration of the Product is to be done by qualified personnel. In Case of Difficulty XWWarning To avoid possible electric shock or personal injury, do not use the Product if it operates abnormally.
