1.0 SAFETY INSTRUCTIONS
Use the calibrator only as specified in the manual, otherwise the protection provided may be impaired.
Do not operate the calibrator in explosive gas, vapor or dust environments.
The calibrator is designed to operate from 24 VDC internal battery source or from the AC adapter that is
Included. Additionally, a smart battery charging system is supplied for charging the internal Nickel Metal
Hydride (NiMH) battery. Do not use AC adapters or chargers other than those supplied with the unit.
When charging the battery from the included battery charger the AC adapter must be plugged into the 24
VDC port on the left side of the unit to enable charging.
If supply external excitation to the Unit Under Test is a measure mode, do not exceed 30 VDC.
There are no user serviceable parts internally, removing the internal cover will void warranty. Return the unit
to the factory for re-certification or repair.
BEST PRACTICES FOR CALIBRATOR OPERATION:
Use the shortest length of tubing from the calibrator to the Unit Under Test, during pressure testing avoid
vibration of the tubing.
Avoid movement of the calibrator during operation, avoid locating in a high vibration environment.
Allow the calibrator to warm-up for one (1) hour before use. The calibrator can be turned on during transport.
2.0 INTRODUCTION
DOCUMENTING PROCESS CALIBRATOR:
The Setra Micro-Cal Model 869 is a pressure generating, very low pressure documenting calibrator. The calibrator has been designed and optimized to meet the needs of our customers for a capable system for the
calibration, troubleshooting and documentation of very low pressure measuring information.
The design of the Model 869 exploits years of experience in the calibration of Setra transducers, as well as
NASA patented and Setra exclusive licensed technology. The Pocket PC user interface provides a familiar
“state-of-the-art” application of computer technology and an upgrade path for future developments.
Major Features:
-Pocket PC user interface, capable of storing thousands of Units Under Test (UUT) data files.
-Portable, battery powered system, capable of full operation for eight (8) hours.
-Closed loop pressure control which is immune to the effects of ambient pressure perturbations, (doors
closing, people moving around).
-Very low internal reference pressure standards, which are matched to the UUT, pressure ranges.
-Auto zero pressure “tare” function.
-Ability to source power to the UUT, or external power supply.
-Strip chart capability for troubleshooting leak and drift conditions.
-Micro-stepping pressure control capable of precise generation and
pressure control in the micro inch of water column pressure ranges.
-Leak testing
-Volume measurement

5.0 CALIBRATION SETUP
5.1 BATTERY CHARGING:
The calibrator is assembled, calibrated and tested at the factory.
The battery, as received, will be in a partially charged state. Before operation please be sure to fully charge
the battery to get maximum portable use of the device.
TO CHARGE THE BATTERY:
-Connect the AC power adapter to AC supply and the 24 VDC connector to the input labeled 24 VDC on the
left side of the calibrator.
-Connect the AC end of the Smart Charger to an AC power source, connect the other end (4 pin circular DIN
connector) of the charger to the battery charger input of the calibrator.
-Initial battery charging will take approximately 2-4 hours. If the battery is discharged below 20 VDC charging
overnight will be required.
5.2 POCKET PC CHARGING
TO CHARGE THE POCKET PC:
-If calibrator is not in use for extended periods of time, Pocket PC should be plugged into HP supplied power
cable.
-Pocket PC will only charge from calibrator when battery is charged or A/C adapter is plugged in. The main
power switch must be in the ON position.
-Pocket PC must remain charged.
-Should the battery on the Pocket PC become drained to the point that the device resets itself, please see the
Pocket PC Backup/Restore information on Page 6 of this manual.

10.0 GLOSSY OF TERMS
Atmospheric Pressure – Pressure of the
atmosphere at the earth’s surface. NIST
standard atmospheric pressure = 1.01325 bar.
P/I – Term common to process industries
meaning pressure-in/current-out. (3-15 PSIG
Input to 4-20 mA DC Output).
Bar – Unit of pressure (or stress). 1 bar =
750.07 mm of mercury at 0°C, lat. 45°.
Burst Pressure – The maximum pressure that
may be applied to the positive pressure port
without rupturing the sensing element.
Capacitive Sensing – Detection and measurement of pressure through the change in voltage
across a capacitor, one plate of which is a
diaphragm which deflects slightly with changes
in applied pressure.
Differential Pressure – Pressure measurement
relative to a reference pressure. Referred to as
pounds per square inch differential (PSID).
FS (Full Span or Full Scale) – The range of
measured values over which a transducer is
intended to measure, specified by the upper
and lower limits. Ex: 0 to 100 PSIG, FS is 100
PSIG/0 to 5 VDC, FS is 5 VDC, 800-1100 MB,
FS is 300 MB.
Pressure Transducer – An electromechanical
device for translating fluid pressure valves into
voltages across a high-impedance (5k ohms or
greater) load.
Pressure Transmitter – An electromechanical
device for translating fluid pressure values into
Currents (generally 4-20 mA) into a low-impedance
load.
Proof Pressure – The maximum pressure that
may be applied without changing performance
beyond specifications (typically 0.5% FS zero shift).
Range – The spread between the maximum and
minimum pressures between which the transducer
has been designed to operate.
Span – The algebraic difference between the limits
of the range. Ex: .1 to 5.1 Volts DC; span is 5 VDC.
Sometimes used to designate full scale output;
i.e. 5 VDC.
