1. Fundamental safety instructions
Avoid electrical hazards:
Never make measurements with the instrument and its probes on or near live com-
ponents unless the instrument is expressly approved for current/voltage measure­ments!
Protect the instrument:
Never store the instrument together with solvents (e.g. acetone).
Product safety/preserving warranty claims:
Operate the instrument only within the parameters specified in the technical data.
Handle the instrument properly and according to its intended purpose.
Never apply force!
Temperatures given on probes/sensors relate only to the measuring range of the sen-
sors. Do not expose handles and feeders to any temperatures in excess of 70 °C unless they are expressly permitted for higher temperatures.
Open the instrument only when this is expressly described in the Instruction Manual
for maintenance purposes.
Carry out only the maintenance and repair work that is described in the Instruction
Manual. Follow the prescribed steps exactly. For safety reasons, use only original spare parts from Testo.
Any further or additional work must only be carried out by authorised personnel.
Testo will otherwise refuse to accept responsibility for the proper functioning of the instrument after repair and for the validity of certifications.
Ensure correct disposal:
Dispose of defective rechargeable batteries and spent batteries at the provided col-
lection points.
Send the instrument directly to us at the end of its life cycle. We will ensure that it is
disposed of in an environmentally friendly manner.
1. Fundamental safety instructions6

2. Intended purpose
Employ the instruments for the following applications only:
The testo 521 and testo 526 instruments are handheld pressure-measuring instru­ments that were developed specifically for use in air conditioning / ventilation equipment, thermal engineering, automotive engineering and industrial plant engineering. The main areas of use and measuring applications are:
testo 521
Air conditioning/ventilation, clean rooms and OPs: Pressure ranges 0 to 100 hPa/0...2,5hPa, Pitot tube measurement, volume flow calcula­tion, pressure drop on filters, fans, ...
testo 526
Industrial pressure measurement: Pressure ranges 0 to 2000 hPa, pressure in compressed air systems, leaks in pipes & lines, pressure drop, vacuum
Both instruments offer the following features:
- Measurement location management
- Data management via testo ComSoft software (from Version 3)
- “on-site” printout of the measured results via the testo printer
- Temperature measurement
- Wide range of probes and sensors can be connected so that one instrument covers as many measuring tasks as possible
Location conditions
Changes in the location and temperature of the instrument and pressure probes have an effect on the measurement results. Bring the instrument and probes into a stable positi­on before any measurement. Do not change this position during measurement. Do not subject the housing to mechanical strains during measurement.
Media compatibility testo 521/526:
Permitted medium: air and non-aggressive gases
External low pressure probes 0638 1347, 0638 1447, 0638 1547, 0638 1647, 0638 1747: Permitted medium: air and non-aggressive gases
External high-pressure probes 0638 1741, 0638 1841, 0638 1941, 0638 2041, 0638 2141: Permitted medium: refrigerant, oil, water, air and non-corrosive gases

4. Commissioning
Charge batteries properly!
Danger of explosion!
Only start the charging process if a recharge-
able battery is in the instrument and Rech. has been set as the battery type.
4.1 Inserting the battery / rechargeable battery
(Rechargeable battery type: NiMH IEC 6F22)
1 Open the battery compartment on the rear of the
instrument.
2 Insert the monobloc battery / rechargeable battery.
Observe +/-.
3 Close the battery compartment.
To avoid the loss of data, it is imperative that you switch the instrument off when changing the battery/rechargeable battery and replace the battery in < 10 min.
4.2
Using the power unit
The instrument can be operated with mains unit 0554 0088, without a battery/rechargeable battery.
The instrument switches on automatically when the power unit is connected.
It is normal for the mains unit to warm up. The mains unit has a thermostatic switch to protect it against overheating.
Caution
Page 13
4.3 Connecting probes/sensors
Connect the probes / sensors before switching the instrument on. Probe-specific characteristics are only read in when the instrument is switched on. Make sure the connections are secure, but do not use force!
Connect the plug/hoses of the probes/sensors to
the corresponding connections of the instrument:
1 Pressure hoses at p+ and p-
Make sure the pressure hose does not jump away from the connection socket!
Risk of injury!
Always use the screw locking device to secu-
re the pressure hose at pressures above 700 hPa.
2 Socket „1“ and socket „2“:
Thermocouple probe (type K), NTC probe, pressu­re probe, power supply cable

For velocity measurement with the Pitot tube, the internal pressure sensor 0 - 100 hPa is the best for velocities from 5 - 100 m/s. For measurements in the range of 1 - 12 m/sec., use the external differential pressure probe 0638 1347 with measuring range 0 - 100 Pa. The velocity v is calculated in the instru­ment from the pressure difference p in the Pitot tube according to the following formula:
v [m/sec.] = S x
200000 x p [hPa]
rho [g/m

]
To activate the velocity rate measurement and volume flow rate calculation, please refer to chapter 6.5.6. Alternatively, it is possible to enter the variables which influence the air density at the measuring location:
- temperature (see point 6.4.1)
- relative humidity (see point 6.4.2)
- absolute pressure (see point 6.4.3)
Additional input options for calculating the velocity or volume flow rate are the
- cross-section (see point 6.4.5)
- offset factor (see point 6.4.6) Calculation formula:
V [m

The steps for performing the tightness test “Test with air”, based on the standard DIN EN1610 “Construc­tion and testing of drains and sewers”, are outlined in the instrument menu:
- Enter the set slowdown time (tSlDoReq)
- Enter the set test time (tTestReq)
- Enter the set test pressure at which the measure­ment is to take place (P Req.)
- Enter the permitted pressure drop p in hPa
that is critical in order to assess whether the pipeline
is leaking or not (P Req.)
The test can start once the required values according to the standard have been entered. It is divided into 5 areas: Time zone areas:
- Pre-fill time
Build-up of the pressure in the pipe system and the
actual duration.
- Slowdown time
Measurement of the pressure, which should exceed
the test pressure required by the standard by about 10 % over 5 min. and which records the actual duration.
- Test time Record of the actual test duration.
- Drop time Record of the duration of the pressure drop in the
line.
When the test has come to an end the individual required and actual test data can be printed out on the printer or automatically imported into a test log via the ComSoft software.
Slowdown time (tSlDoReq)
Set the required time. According to DIN EN1610, it should be about 5 min.: A starting pressure that exceeds the necessary test pressure p
o by about 10 %. po must first be main-
tained for 5 min. 4 Select tSlDoReq (0 sec. to 99 min., 59 sec.) with

7.1 Zeroing the display
The measurement values can be falsified by a
change in the position of the measuring instrument. After zeroing, the position of the measuring instrument must not be changed. Carry out zeroing before every measurement in order to compensate faulty positi­oning or long-term zero-point drift. For the display of the internal pressure to be zeroed, the instrument must be in the measurement menu and there must be a differential pressure of < 2.5 % of the full-scale value (at testo 5213 reset <20% of the full scale value).

Danger of explosion!
Only start the charging process if a recharge-
able battery is in the instrument and Rech. has been set as the battery type.
The battery in the instrument can only be rechar­ged if it is a rechargeable battery and Rech. is set as the battery type.
1 Make sure a rechargeable battery is in the instru-
ment.
2 Make sure that Rech. is set as the battery type
(see 6.6.3 Bat. type).
3 Connect the connector of the mains unit to the
12 V jack of the instrument.

8.3 Cleaning the instrument
If the housing of the instrument is dirty, clean it with
a damp cloth. Do not use any corrosive cleaning agents or solvents! Weak household cleaning agents and detergents may be used.
