FUNCTIONS

To ensure safe and accurate operation, please be familiar with the following operations and functions.

WARNING: Severe injury or damage can occur through improper use of pressure instruments! Do not exceed recommended pressure limits of

tubing and ttings. Be certain all pressure connections are secured. Never disconnect pressure instrumentation without rst relieving

stem pressure.

CAUTION: Never insert any object (other than a 1⁄8" NPT tting) into the inlet ports. The sensor diaphragm is very thin and can be damaged or

destroyed by solid or sharp objects. Clean the sensor with appropriate solvents, only.

he internal pressure sensor measures the dierence between atmospheric (barometric) pressure, and the pressure (or vacuum) applied to the pressure port.

The pressure being measured can be either liquid or gaseous, providing it is compatible with the materials listed in the specication section.

PTFE tape should be used with any ttings installed into either of the 1⁄8" female NPT ports. Two ports are provided so that additional tees should not be

required. Plug any unused ports.

MultiCals have been calibrated for use with meters that have 10MΩ input impedance, as do most handheld meters, and some benchtop multimeters. If your

meter has higher or lower input impedance, add 0.1% to the specication of the MultiCal, or refer to the Calibration section of this manual for other methods

of eliminating the error introduced by an impedance mismatch.
