Setting-up

Supplying Power to the Model 5825 DP-Calc™ Micromanometer
The Model 5825 is powered by four size AA batteries.

Installing the Batteries
Insert four AA batteries as indicated by the diagram located on the inside of the battery compartment. The Model 5825 is designed to operate with either alkaline or NiMH rechargeable batteries, although it will not recharge NiMH batteries. Battery life will be shorter if NiMH batteries are used. Carbon-zinc batteries are not recommended because of the danger of battery acid leakage.
Using the Optional AC Adapter
When using the AC adapter, the batteries (if installed) will be bypassed. Be sure to provide the correct voltage and frequency, which is marked on the back of the AC adapter. The AC adapter will not recharge the batteries.

Connecting to a Computer
Use the Computer Interface USB Cable to connect the instrument to a computer.
CAUTION
This symbol is used to indicate that the data port of the Model 5825 IS NOT intended for connection to a public telecommunications network. Connect the USB data port only to another USB port.

Operation

Keypad Functions

ON/OFF Key	Press to turn the Model 5825 on and off. During the power up sequence the display will show the following: Model Number, Serial Number and Software Revision.
Arrow () Keys	Press to scroll through choices while setting a parameter.
(Enter) Key	Press to accept a value or condition.
Arrow () and Menu Soft Keys	Press arrow keys to change choices while setting a parameter. Press the Menu soft key to select the Menu selections, which are Display Setup, Pressure Zero, Settings, Flow Setup, Actual/Std Set up, Data Logging, and Calibration.

Common Terms
In this manual there are several terms that are used in different places. The following is a brief explanation of the meanings of those terms.

Sample	Consists of all of the measurement parameters stored at the same time.
Test ID	A group of samples. The statistics (average, minimum, maximum, and count) are calculated for each test ID. The maximum number of test IDs is 100.
Time Constant	The time constant is an averaging period. It is used to dampen the display. If you are experiencing fluctuating flows, a longer time constant will slow down those fluctuations. The display will update every second, but the displayed reading will be the average over the last time constant period. For example, if the time constant is 10 seconds, the display will update every second, but the displayed reading will be the average from the last 10 seconds. This is also referred to as a “moving average”.

Log Interval

The logging interval is a frequency period that the instrument will log readings. For example, if the logging interval is set to 30 minutes, each sample will be the average of the last 30 minutes.

Menus

DISPLAY SETUP
Display setup menu is where you will setup the desired parameters to be displayed on the running screen. With a parameter highlighted you can then use the ON soft key to have it show up on the running screen or select the OFF soft key to turn off the parameter. Use PRIMARY soft key to have a parameter show up on the running screen in a larger display. Only one parameter can be selected as a primary, and up to 2 secondary parameters can be selected at one time.

PRESSURE ZERO
Turn the instrument on for a minimum of five minutes to let it warm up before zeroing the pressure sensor. To zero the pressure reading, select the Pressure Zero menu. The instrument will indicate if the pressure zero was successful.

SETTINGS
Settings menu is where you can set the general settings. These include Language, Beeper, Select Units, Time Constant, Contrast, Set Time, Set Date, Time Format, Date Format, Number Format, Backlight and Auto Off. Use the soft keys to scroll through the settings for each option and use the key to accept settings.

FLOW SET UP

In Flow Setup mode, there are four types: Round Duct, Rectangle Duct, Duct Area, and K-Factor. Use the soft keys to scroll through the types and then press the key to accept the desired type. To change the setting, highlight the Enter Settings option and press the key.
Press/Kfact allows for calculating flow rate from diffusers or flow stations with pressure taps using the instrument’s pressure ports and Kfactors. The K-factors are obtained from the diffuser or flow station manufacturer. For more information, refer to Application Note TSI-114.
- Up to 5 K-factors can be pre-programmed for quick use.
- When Flow is set as the Primary measurement in the Display Setup menu, the K-factor will also be displayed.

When measuring Flow as the Primary measurement, the parameters can be quickly changed by pressing the key while on the main measurement screen. Make adjustments with the arrow keys and press to accept, or enter the Select Kfactor menu to choose a different pre-programmed flow value.

ACTUAL/STANDARD SETUP
Choose Actual/Standard measurements and parameters in the Act/Std Setup menu. Within this menu, the user can also select Standard Temperature, Standard Pressure, and a source for the actual temperature. The actual barometric pressure must be entered to convert air velocity and volume measurements to actual conditions. The Entered Temp range is from -40 to 1832°F (-40 to 1000°C).

DATA LOGGING

Measurements
Measurements to be logged are independent of measurements on the display, and must therefore be selected under DATA LOGGING → Measurements.
- When set to ON, measurement will be logged to memory.
- When set to DISPLAY, measurement will be logged to memory if it is visible on the main running screen.
- When set to OFF, measurement will not be logged to memory.
Log Mode/Log Settings
You can set Log Mode to Manual, Auto-save, or Cont-key.
- In Cont-key mode, the user starts taking readings and logging by pressing the key. The instrument will continue taking measurements until the key is pressed again.
- Auto-save and Cont-Key modes have the following additional
  - Auto-save Log Interval
  - Cont-key Log Interval
- Pressing the keys simultaneously will lock the keypad to prevent unauthorized adjustments to the instruments. To unlock the keypad, press the keys simultaneously.
Delete Data
Use this to delete all data, delete a test, or delete a sample.
% Memory
This option displays the memory available. Delete All, under Delete Data, will clear memory and reset the memory available.

LogDat2TM Downloading Software

LogDat2™ software can be downloaded from the TSI Software and Firmware Wizard | TSI page. Once downloaded onto your PC, click the application file to begin installation. Follow the on-screen instructions to install the software.
To download data from the Model 5825, connect the supplied computer interface USB cable to the Model 5825 and a computer USB port. Then run the LogDat2™ downloading software. Within the LogDat2 software, either select the tests to be downloaded or double-click on a test to open it.

Maintenance

The Model 5825 requires very little maintenance to keep it performing well.

Recalibration

To maintain a high degree of accuracy in your measurements, we recommend that you return your Model 5825 to TSI® for annual recalibration. Please contact one of TSI®’s offices or your local distributor to make service arrangements and to receive a “Service Request” number. To fill out an online “Service Request” form, visit TSI®’s website at tsi.com/service.

The Model 5825 can also be recalibrated in the field using the CALIBRATION menu. These field adjustments are intended to make minor changes in calibration to match a user’s calibration standards. The field adjustment IS NOT intended as a complete calibration capability. For complete, multiple-point calibration and certification, the instrument must be returned to the factory.

Cases
If the instrument case or storage case needs cleaning, wipe it off with a soft cloth and isopropyl alcohol or a mild detergent. NEVER immerse the Model 5825. If the enclosure of the Model 5825 or the AC adapter becomes broken, it must be replaced immediately to prevent access to hazardous voltage.

Storage
Remove the batteries when storing the unit for more than one month to prevent damage due to battery leakage.
