Warning danger:
Read, before you perform any action in connection with the tester, this
user manual carefully. Mors Smitt B.V. is not liable for injuries, (nancial)
damage and excessive wear resulting from incorrectly performed
maintenance, incorrect use of or modications to the tester.
Attention:
Under certain circumstances, in almost every electronic memory data
can be lost or changed. Therefore Mors Smitt B.V. accepts no nancial
responsibility for losses or claims by lost or otherwise unusable
information resulting from abuse, misuse, failure, neglect of the user
manual and procedures or other related causes.
Attention:
The EazyPV red and black 4 mm test terminals may be used to make

to earth. Do not connect the EazyPV to voltages which may exceed
this rating.
Attention:
The PV-testterminals maximum rating: 1000 VDC open circuit voltage,
10 A short circuit current. Do not exceed this rating. The DC supply
must be isolated from earth during testing.
Attention:
High voltages are present at the probe tips of the EazyPV during
insulation resistance measurement. Always hold test probes behind
the hand guards.
Attention:
Check the EazyPV and all associated cables and leads before operating
the equipment. Do not use if there are signs of damage. Only use the
test leads supplied with the EazyPV.
Attention:
Do not touch any exposed metal parts of the PV-installation
during testing.

Attention:
Press and hold the buttons a few seconds to turn the tester on/o
4.3 Battery condition
The EazyPV automatically performs a battery condition check whilst idle and during
measurements. When the battery level is low, the battery symbol icon will appear on the
display. The EazyPV will continue to function, however the batteries should be replaced.
Tip:
When the battery symbol icon is ashing all tests will be inhibited and
the batteries immediately must be replaced as described in section 7.3.

5. EazyPV tests
5.1 Protective earth resistance measurement (Rpe)
5.1.1 Test lead resistance null
The EazyPV can automatically compensate for the resistance of the test leads as follows:
1. Hold the tips of the test probes rmly
together as shown, to ensure a good
electrical connection
2. Press and hold the ‘Null’ key
3. The measured resistance of the test leads
is shown in the primary display until
a beep is heard
4. The Rpe display will now 0.00 and the
Null icon is illuminated
Attention:
For ease of use, the EazyPV will store the lead compensation when
switched o and recall this value when next switched on. The stored
value is only applicable to the test leads used when the compensation
measurement was made. If the test leads are replaced the Rpe null
function should be repeated using the replacement test leads.
Attention:
A maximum test lead resistance of 10 Ω ohms can be taken into
account. If the test lead resistance is greater than 10 Ω an error beep
will indicate that the lead zero function has failed.

2. The EazyPV will automatically measure the voltage between the probes
3. The polarity of the voltage is shown using the icon next to the Rpe icon (if the
measured voltage is AC, alternating + and – is shown)
Tip:
When the measured voltage exceeds the 30 V limit, the voltage icon
is shown

5.3 Auto sequence measurement
1. Connect the EazyPV to the PV-module as shown, using the supplied test lead
adaptors
2. The red test probe should be connected to earth. Where the structure/frame is
bonded to earth, the earth connection maybe to any suitable earth or to the array
frame
3. Where the array frame is not bonded to earth, a commissioning engineer may
choose to do two tests:
a. Between array cables and earth
b. Between array cables and frame
4. The EazyPV will automatically detect any DC-voltage connected to the PV-test
socket inputs 8 and 9 and display the measured voltage
5. If the PV-voltage polarity is reversed, the polarity indicator will ash a cross next to
the voltage icon
6. If the incoming voltage is >30 v then the shock hazard icon will ash
7. Use the Viso button to select either the 250 V, 500 V or 1000 V insulation test
voltage

8. Press the auto button and the EazyPV will automatically perform the
following tests:
• Open circuit voltage
• Short circuit current
• Insulation resistance
9. The measurement results will remain on the LCD for 20 seconds or until a key is
pressed
10. A tick or cross will be displayed next to the insulation resistance measurement
indicating whether the result is above or below the threshold values shown.
Table 1
Viso Limit
250 V 0.5 MΩ
500 V 1.0 MΩ
1000 V 1.0 MΩ
Attention:
Always ensure that the circuit under test is electrically isolated from
the mains supply.
Tip:
Due to the high input impedance of the red 4 mm test terminal,
voltage caused by leakage currents may be detected on the prior to
starting a test.
Tip:
During the insulation test, the EazyPV applies a short circuit across
the PV-string. The insulation test voltage is then applied between the
red 4 mm test lead and the two PV-testterminals.
Tip:
If the DC-voltage polarity is incorrect or the voltage is < 5 V or >1000 V
the Autotest will be inhibited until the problem is corrected.

shown.
1. Disconnect all cables from the PV test inputs (connection 8 & 9 in gure 2)
2. Connect the current clamp to the red – black 4 mm probe inputs.
3. Move the current clamp switch to the 40 A position
4. Zero current clamp according the manual of the clamp
5. Place the clamp around the DC-cable of the solar installation
6. Press the Viso button until the clamp icon appears on the LCD
