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.

5.4 GETTING STARTED

-Open calibrator top.

-Turn on calibrator power (power switch on right side of the calibrator).

-Once calibrator is powered up, re-zero function begins automatically, Please wait for completion. (User will hear operation of solenoid valves and stepper motor).

-Look for orange light (flashing or solid) on PDA (if light does not come on, see section on battery charging.

-Turn on PDA power (button in upper right-hand corner of the PDA).

-After powering up, tap the icon labeled programs folder and

CALIBRATOR icon).

-Software will start up with Real Time page. Tap

CALIBRATOR, (tap START MENU icon,

VENT button (diagram 6)

to leave the calibrator in a ready to “hook-up” state.
