6 Power supply

The PCE-HLD 10 can be powered either by 4 1,5V AA batteries or via the 5 V DC USB interface.

6.1 Power supply via the micro-USB interface

The PCE-HLD 10 can be supplied with a 5 V DC, 1 A fixed voltage source via the micro-USB
interface.

Note:

This interface is not a data interface. The inserted batteries can also not be recharged via this
interface.

6.2 Power supply via batteries

To supply power from batteries, open the battery compartment on the back. Then insert four 1.5
V AA batteries. Ensure correct polarity when inserting them. After inserting the batteries, close
the battery compartment.
As soon as the batteries are discharged, this is signalled by the battery status indicator lighting
up. As soon as this indicator lights up, the batteries must be replaced with new ones to ensure
proper functioning.

7 Switching the meter on/off

To switch the meter on or off, press and hold the on / off key for at least 2 seconds. After switching
on, the meter requires a warm-up time of 45 s until it is ready for operation. The warm-up time is
signalled by all LEDs flashing. As soon as the flashing stops, the meter is ready for measurement.

Note:

Zeroing is carried out during the warm-up period. Therefore, make sure that the meter is switched
on in fresh air. If the meter is zeroed when hydrogen is present, this hydrogen content is ignored
in subsequent measurements until a new zeroing is performed.

7.1 Automatic power off

If no key is pressed for 10 minutes, the meter turns off. To disable this function, press and hold
the key when turning on the meter. After switching on, you can release the keys. The meter

will now no longer switch off automatically. The automatic power off function will be active again
after manual switch-off.

8 Sensitivity setting

To set the sensitivity, press the key repeatedly until you have reached your desired sensitivity.
The smaller the sensitivity has been selected, the larger the measurement range on the bar graph.
As a result, the meter may not display anything for small amounts of hydrogen. With a high
sensitivity, the measurement range of the bar graph will be exhausted quickly. Set the sensitivity
according to your application.

9 Zeroing

When the meter is switched on, it is zeroed automatically.
Only switch on the meter in a non-polluted environment. Switching it on in a polluted environment
will cause incorrect measurements and any H2 leakage will not be detected.
During operation, the sensor is always adjusted to the set zero point in order to filter out any
background gases that may occur.

To switch off this function, press and hold the key for two seconds. To enable this function
again, press and hold this key again for two seconds. The reset indicator shows whether the
function is switched on. As soon as the control LED lights up, the function is activated.

9.1 Manual zeroing

To perform a manual zeroing, press the reset key once.

Note:

Make sure that the meter is zeroed in fresh air. If it is zeroed with hydrogen present, this hydrogen
content will be ignored in subsequent measurements until a new zeroing is performed.

10 Replace sensor

The sensor has a lifetime of approx. 1 year. Obsolete sensors may cause faulty measurements
or existing leaks may not be detected. High concentrations can reduce the lifetime of the sensor.
Replacement sensors can be found directly on https://www.pce-instruments.com.
To replace the sensor, first switch off the meter. Then loosen the sensor protection. Then pull off
the sensor and replace it with a new one. Then check whether the filter inside the sensor protector
is clean and whether there is any damage to the sealing ring. If there is damage or dirt, it must be
eliminated.

Note:

The sensor heats up during operation and could possibly cause burns. Therefore, let the sensor
cool down for a short time.

11 Contact

If you have any questions, suggestions or technical problems, please do not hesitate to contact

us. You will find the relevant contact information at the end of this user manual.

12 Disposal

For the disposal of batteries in the EU, the 2006/66/EC directive of the European
Parliament applies. Due to the contained pollutants, batteries must not be disposed of as
household waste. They must be given to collection points designed for that purpose.

In order to comply with the EU directive 2012/19/EU we take our devices back. We either re­use them or give them to a recycling company which disposes of the devices in line with law.

For countries outside the EU, batteries and devices should be disposed of in accordance
with your local waste regulations.

If you have any questions, please contact PCE Instruments.
