1.0 FEATURES The SRIMV is a multi-mode (air velocity, flow, pressure, temperature and humidity) monitor. It has a 3 color backlight display, a digital input for a door switch, 2 analog inputs for temperature and humidity, 1 relay output for remote alarm indication and an internal pressure sensor. It can display and alarm on Velocity, Flow, Pressure, Temperature and Humidity parameters.

Display Parameters Unit in the normal state, line 1 indicates differential pressure, velocity or flow and the corresponding engineering units. Line 2 indicates the temperature and humidity reading, if enabled. The green backlight indicates that the velocity (or pressure or flow), the temperature and humidity is within the allowable alarm limits.
Menu Operation Menu key – Provides access to the menu structure Down arrow key – Allows selection of numerical parameters. Pushing the down arrow causes the digits to move upwards in a 1 digit count and will wrap around. The cursor below the indicated item in the current menu item indicates that this is the digit that is being changed.

Velocity, Flow, Pressure, ACH Selection User Selectable for Velocity, Flow, Pressure or Air Changes per Hour. Whichever option is chosen in this menu will be shown as the default in the secondary menu under the V/Flow/Pressure section. Choose “enter” to activate the V/Flow/Press menu.
Page 16
Password Enable Enables or disables the 4 digit numeric password. Filter Setting (0-99) is the filter setting. This is the number of samples used to take an average; it is a weighted rolling average, so the higher the number the more filtering is done to smooth out the output and display readings.
Page 17
Temperature Source Choose between an analog sensor input (from external sensor) or “set-up”. The sensor input comes from the external sensor, whereas the “set-up” option is added manually if there is no temperature sensor used. Temp is used to calculate air density; Default is 70 degrees Fahrenheit or 21.1 degrees Celsius.

Velocity Alarm Low Limit Sets the alarm for the low side velocity limit. Choose “enter” to activate the V Alarm L Limit menu. The menu will flash, then press the “down arrow” to select desired digit. Press “enter” to select and move to next digit. Velocity Alarm Enable Enables or disables the velocity Alarm.
Page 19
Barometric Pressure Set current barometric pressure conditions. This can either be entered manually or it will be set to the standard default of 29.92 in Hg. Barometric Pressure effects the flow rate due to changes in air density. Choose “enter” to activate the Barometric Pressure menu.
Page 20
Duct Area Manually enter the area of the duct where the probe is mounted. The ducts area is necessary for calculating the flow rate. The menu will flash, then press the “down arrow” to select desired digit. Press “enter” to select and move to next digit.
Page 21
Pressure Alarm Low Limit Sets the alarm for the low side pressure limit. Choose “enter” to activate the P Alarm L Limit menu. The menu will flash, then press the “down arrow” to select desired digit. Press “enter” to select and move to next digit. Pressure Alarm Enable Enables or disables the Pressure Alarm.

If Air Changes per Hour is Selected After choosing to display and monitor Air Changes Per Hour from the Common Config section, set the parameters for that output. K Factor The K factor is provided by the manufacturer of the static pressure probe or Pitot tube and varies by probe length.
Page 23
Zero Calibration “Tares” out any Zero pressure error. This must be done with Zero pressure applied to the unit. Duct Area Manually enter the area of the duct where the probe is mounted. The ducts area is necessary for calculating the flow rate. The menu will flash, then press the “down arrow”...

ACH Range Enter Range of ACH for the analog output. ACH range is proportional to the chosen output. Temperature Selection Menu Temperature Runs through the Temperature setup screen to set all parameters to desired set points. Temperature Enable Enables or Disables the Temperature Setting. Choose “enter”...
Page 25
Temperature Max Vin Input the maximum temperature that corresponds to the max analog output- T_Max Vin. Choose “enter” to activate the T Max Vin menu. The menu will flash, then press the “down arrow” to select desired digit. Press “enter” to select next digit.
Page 26
4. Humidity Selection Menu Runs through the Humidity setup screen to set all parameters to desired set points. Humidity Enable Enables or disables humidity setting. Choose “enter” to activate the Humidity Enable menu. The menu will flash, then press the “down arrow” to select desired mode.
Page 27
Humidity Max Vin Input the maximum humidity that corresponds to the min. analog output- H Max Vin. Choose “enter” to activate the H Max Vin menu. The menu will flash, then press the “down arrow” to select desired digit. Press “enter” to select next digit.

Examples for Setting up Menu Example 1: Output mode setting To enter the menu, press the Menu key to view “Common Configuration. Next, press the ← button twice until the indicates output mode. 4-20 mA is the default output mode, if you want to change display to 0-5Vdc or 0-10Vdc press the down arrow and press the return key to select.
Page 29
Example 3 Calibration Remove the tubes from the pressure ports or shut of fans to the room and open the door so that zero differential pressure is applied to the monitor. Select menu item ZERO CALIBRATION. The display shows the current pressure value, press the Enter key.
