Setra Micro-Cal 869 Specifications

Accuracy

● Highest accuracy to support certification of all low DP critical process pressure sensors

● True low range dual reference pressure sensors with NIST traceability

● Dual reference design provides maximum accuracy, repeatability and resolution

Pressure Generation

■ User selectable automated pressure generation profiles with up to 101 calibration points

■ NASA patented low pressure generating technology achieves ±0.0002 in. W.C. low

pressure regulation - micro in. of W.C. per step resolution

■ True differential pressure generation - both high and low pressure ports connect to the
unit under test, providing isolation from process background disturbances

■ True zero pressure generation - high and low pressure ports shorted to produce stable,
noise-free zero pressure input - outperforms competitive active zero pressure systems

Key Features

SIMPLE STEP-BY-STEP INTERFACE

• Easy step-by-step user interface process

• Designed with built-in leak test function

• Provides accuracy and stability plots

Simple Pocket PC
User Interface

Step 1
UUT (Unit Under Test) Setup

- Select transducer profi le

- Select accuracy specifi cation

- Select output (VDC or mA)

Step 2
Real Time

- View current pressure and out­ put for testing and calibration

- Apply selected pressure to per­ form adjustment (zero, span or
linearity)

• Handles multiple engineering units

• Both pressure generation and monitoring
modes to verify system performance

Calibration management database

• Store and retrieve transducer profi les

• Generate as found and as left calibration data

• Print calibration certifi cates

Step 3
Test Unit

- Return to screen to perform
calibration test sequence

- Review and record results

- Copy and save data into
your calibration database

Portability & Versatility

■ AC or battery operation - eight hours of operation on full battery

■ Rugged, compact carrying case - great for cramped and

remote locations

■ Calibrate diffi cult-to-reach devices in-situ (ceilings,
ducts, etc.) with electro-pneumatic harness
assembly - for analog tranducers, 2, 3 and 4-wire,
confi gurable length

869 Expert System

For even greater savings and security, upgrade to
the 869 ‘Expert’ Automatic Calibration System*

Features

Fully Automated, Hands-Off Calibration reduces

●

calibration times by 2/3 or more. No tube cutting or wire
removal is required.

●

Easy-to-Use, Smart Communication Software pro-
vides transducer detection and automated calibration with
Setra’s digital transducers and room pressure monitors.

●

Electropneumatic Interface Cable (EPIC) allows the
869 to simultaneously pressurize a 269 or SRPM under test
and automatically transmit ID and calibration data between
the two units.

●

Two EPIC Cable Lengths Offered: 6ft (standard) & 12ft
(optional), providing easy access to units located in remote,
difficult to access areas.

Expert System: EPIC, SRPM, 269 & 869

Easily Upgrade Original 869 - simply send in your unit
and it will be returned with the installed Expert System.

This is especially convenient if performed when your 869 is in
the factory for it’s annual recertification.
