Setting-up
Supplying Power to the Model 5815 DP-CALC Micromanometer
The Model 5815 is powered with 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 5815 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.

Operation
Keypad Functions
ON/OFF Key Press to turn the Model 5815 on and off. During
the power up sequence the display will show the
following: Model Number, Serial Number,
Software Revision and Last Date Calibrated.
ft/min / m/s Key Pressing this key changes the display to read air
velocity, converted from.
in H2O / Pa / hPa /
kPa / mm HG Key
Pressing this key changes the display to read
differential pressure.
0 Key Pressing the 0 key zeroes the pressure
measurement.
Changing Units To change units, first put the desired measurement
(air velocity or temperature) on the display. Then
press and hold the left, unlabelled key for five
seconds. Finally, use the ST and ENTER key to
select the units.

for common problems encountered with the Model 5815. If your symptom is
not listed, or if none of the solutions solves your problem, please contact
TSI.
Table 5-1: Troubleshooting the Model 5815
Symptom Possible Causes Corrective Action
No Display Unit not turned on Switch unit on.
Low or dead batteries Replace batteries.
Dirty battery contacts Clean the battery
contacts.

Specifications
Specifications are subject to change without notice.
Static/Differential Pressure:
Range1: -15 to +15 in. H2O (-28.0 to +28.0 mm Hg, -3735 to
+3735 Pa)
Accuracy: ±1% of reading ±0.005 in. H2O (±0.01 mm Hg, ±1 Pa)
Resolution: 0.001 in. H2O (1 Pa, 0.01 mm Hg)
Velocity From a Pitot Tube:
Range2: 250 to 15500 ft/min (1.27 to 78.7 m/s)
Accuracy3: ±1.5% at 2000 ft/min (10.16 m/s)
Resolution: 1 ft/min (0.1 m/s)
Instrument Temperature Range:
Operating (Electronics): 40 to 113°F (5 to 45°C)
Storage: -4 to 140°F (-20 to 60°C)
Instrument Operating Conditions:
Altitude up to 4000 meters
Relative humidity up to 80% RH, non-condensing
Pollution degree 1 in accordance with IEC 664
Transient over voltage category II
External Meter Dimensions:
3.3 in. ×7.0 in. ×1.8 in. (8.4 cm ×17.8 cm ×4.4 cm)
Meter Weight:
Weight with batteries: 0.6 lbs (0.27 kg)
Power Requirements:
Four AA-size batteries (included)
1Overpressure range = 7 psi (190 in. H2O, 360 mmHg, 48 kPa).
2Pressure velocity measurements are not recommended below 1,000 ft/min (5 m/s) and are
best suited to velocities over 2000 ft/min. Range can vary depending on barometric
pressure.
3Accuracy is a function of converting pressure to velocity. Conversion accuracy improves
when actual pressure values increase.
