Fluke ProcessMeter 789 Calibration Manual page 7

•
Remove all probes, test leads, and accessories before the battery door is
opened.
•
Remove all probes, test leads, and accessories that are not necessary for
the measurement.
•
Do not exceed the Measurement Category (CAT) rating of the lowest rated
individual component of a Product, probe, or accessory.
•
Do not use test leads if they are damaged. Examine the test leads for
damaged insulation and measure a known voltage.
•
Do not use a current measurement as an indication that a circuit is safe to
touch. A voltage measurement is necessary to know if a circuit is
hazardous.
•
Do not use the Product if it is altered or damaged.
•
Do not use in CAT III or CAT IV environments without the protective cap
installed on test probes. The protective cap decreases the exposed probe
metal to <4 mm. This decreases the possibility of arc flash from short
circuits.
To prevent damage to the Product or the test equipment:
•
Disconnect the power and discharge all high voltage capacitors
before testing resistance, diodes, or continuity.
•
Use the proper terminals, switch setting, and range for the
measurement or sourcing applications.
