LYCEBELL S8830 Digital Manometer Gas Pressure Tester User Manual

1. Introduction

The LYCEBELL S8830 Digital Manometer is a high-precision instrument designed for measuring single-pipe air pressure or differential pressure between two pipes. It features a large LCD display with backlight, data storage, data hold, and 12 selectable measurement units. This device is suitable for various applications including natural gas pipelines, HVAC systems, mechanical hydraulics, mining, petrochemicals, and industrial smelting.

Key features include:

• Dual-port design for single or differential pressure measurement.
• Large HD LCD display with backlight for clear readings in various lighting conditions.
• Automatic shutdown after 10 minutes of inactivity to conserve battery life.
• Data storage for up to 99 measurements, data hold, zeroing, and MAX/MIN/AVG data collection.
• High accuracy of ±0.3%FS and fast response time of 0.1 seconds.
• 12 selectable measurement units: kPa, bar, mbar, PSI, inHg, mmHg, ozin², inH²O, ftH²O, cmH²O, mmH²O, kgcm².

• Power On/Off Button: Turns the device on or off.
• DIF Button: Activates differential pressure mode or deletes recorded data.
• MAX/MIN/AVG Button: Cycles through maximum, minimum, average, and normal measurement display modes.
• UNITS Button: Changes the measurement unit.
• REC Button: Initiates record saving mode.
• HOLD/Backlight Button: Holds the current data reading or activates/deactivates the backlight.

3. Setup

3.1 Battery Installation

The S8830 Manometer requires three AAA 1.5V batteries for operation. Ensure correct polarity when inserting the batteries.

1. Locate the battery compartment cover on the back of the device.
2. Open the battery compartment.
3. Insert three AAA 1.5V batteries, observing the polarity markings (+/-).
4. Close the battery compartment cover securely.

3.2 Connecting Pressure Hoses

Connect the provided rubber tubes to the positive and negative pressure input ports as required for your measurement application.

• For single-pipe pressure measurement, connect the tube to either the positive or negative input port.
• For differential pressure measurement, connect one tube to the positive input port and another to the negative input port.
• Ensure connections are secure to prevent leaks.

4. Operating Instructions

4.1 Power On/Off

Press the Power On/Off button to turn the manometer on. Press and hold the same button to turn it off. The device will automatically shut down after 10 minutes of inactivity.

4.2 Unit Selection

Press the UNITS button to cycle through the 12 available measurement units: kPa, bar, mbar, PSI, inHg, mmHg, ozin², inH²O, ftH²O, cmH²O, mmH²O, kgcm². Select the unit appropriate for your measurement.

4.3 Differential Pressure (DIF) Mode

To measure the differential pressure between two points, connect the higher pressure source to the positive input port and the lower pressure source to the negative input port. Press the DIF button to activate differential pressure mode. The display will show the pressure difference.

4.4 Data Hold and Backlight

Press the HOLD button to freeze the current reading on the display. Press it again to release. To activate or deactivate the backlight, press and hold the HOLD button.

4.5 MAX/MIN/AVG Measurement

Press the MAX/MIN/AVG button repeatedly to cycle through the maximum, minimum, and average pressure readings recorded during a measurement session. The display will indicate the current mode (MAX, MIN, AVG, or normal).

4.6 Data Recording (REC)

The manometer can store up to 99 sets of measurement data. Press the REC button to enter recording mode. The device will save the current reading. To view recorded data, press the REC button again and use the DIF button to scroll through records. To clear recorded data, press and hold the DIF button while in recording mode.
