GENERAL OVERVIEW SECTION 1
1.1 INTRODUCTION
GENERAL DESCRIPTION
The heart of the Blood Pressure Calibration Kit is a Digimano 1000 series Pressure
Meter. The Digimano 1000 is a portable digital instrument designed to measure the
pressure and vacuum of non-corrosive fluids and gases. The versatile instrument
presents its measurement results in one of two engineering units on a large 3 _ digit
LCD display.
The Blood Pressure Calibration Kit contains the 200-2000IN,
The Digimano 1000 has an accuracy of 0.25% full scale. Seven models with different
engineering units and pressure ranges are available. To provide superior performance,
the Digimano 1000 incorporates one of the latest semiconductor pressure sensors.It is
powered by one 9-Volt alkaline battery.
Optionally, an AC adapter may be used. The Digimano 1000 is CE marked and is
shipped with a Certificate of Calibration traceable to the NIST. The Digimano 1000 is
a rugged instrument that performs its measurements quickly, accurately, and with
ease.

2.2 TYPICAL CALIBRATION SET UP
Place the cuff in a rigid enclosure such as a tin can. Using the inflation bulb pump unit to 200
mmHG and hold. Pressure should remain steady. If it does not stay steady go to Section 3 and
use the same technique to determine where the system is leaking. The bulb, cuff and
connecting hose can all leak and may require removal.
Remove any hoses from your sphygmomanometer (Unit Under Test (UUT)) and inspect them
for cracks. If cracks are present replace hose.
Inspect the Unit Under Test (UUT) for indications of impact or physical damage.
If the UUT is an aneroid style, Sphygmomanometer, ensure that the needle is with the
rectangular zero indicator (11), see Figure 2. If not the unit requires repair prior to
proceeding.
Turn your digital pressure meter on and insure that the display (1) reads zero, if it does not
adjust to zero by using the zero adjustment. See Figure 1.
Adjust the plunger on the Pressure Applicator Syringe to to its mid point by pushing or
pulling the plunger (8) while pressing in the lead screw release button (7), see Figure 2.
Connect the silicon tubing to both the UUT and the Pressure Meter as shown in Figure 3.
Ensure both the UUT and the Pressure Meter read zero, then carefully attach the Pressure
Applicator Syringe, while ensuring that both the UUT and the Pressure Meter remain at zero.
During the remainder of the tests ensure the needle on an aneroid sphygmomanometer travels
smoothly at all times.
Turn the fine adjustment knob (8) Figure 2, until the UUT reads 100 mmHg and hold. Ensure
that the reading remains steady, if the pressure drops refer to section 3.0 Troubleshooting.

By turning the fine adjustment knob apply three values such as 50, 150 300 plus zero. Ensure
that both the sphygmomanometer and digital pressure meter read within 3 mmHG of each
other.

3.0 TROUBLESHOOTING THE CALIBRATION SET UP
3.1 Maintaining Initial Zero readings
The sphygmomanometer and/or the digital pressure meter reads a pressure
after connecting all the tubing and devices.
Make sure that you use the male luer lock fitting when connecting either the
digital pressure meter or the pressure applicator syringe. Always connect the
sphygmomanometer first and the syringe last using care to not induce pressure
into the setup.

Do not readjust zero using the zero adjust on the digital meter, zero can
only be adjusted when the unit is open to atmosphere.
3.2 Maintaining A Steady Pressure Reading
If the sphygmomanometer and the digital pressure meter will not stay steady
your calibration set up is leaking.
Using a clamp or some other tool that will seal off the silicon tubing,
clamp tubing segment (c) at the syringe. If the pressure remains steady
tighten up the syringe connection.
If this fails clamp tube segment (c) at the TEE Connector if pressure
stays steady tighten up this connection.
Else clamp segment (b) at the TEE connector. If pressure stays steady
tighten up this connection.
Else clamp segment (b) at the Digital Pressure Meter connection. If
pressure stays steady tighten up this connection.
Else clamp segment (a) at the TEE connector. If pressure stays steady
tighten up this connection.
Else clamp segment (a) at the Sphygmomanometer connection. If
pressure stays steady tighten up this connection.
