MI 2087 AL2 EasiTEST Measurement instructions

Step 3
q Press the START key and release it. Measurement will be carried out and
result displayed afterwards.
q Check calculated prospective short-circuit current by pressing the DISPLAY
key.
The current is calculated as follows: Ipsc = Un⋅1.06 / RL-PE
Where:
Un = 115V (100V ≤ UL-PE < 160V)
Un = 230V (160V ≤ UL-PE ≤ 264V)
If RCD trips during contact voltage measurement blinking “rcd” message will be
displayed blinking way.
Notes:
q Nominal input voltage range is 100 V ÷ 264V. If input voltage is out of the
range, the voltage value equipped with “!” mark will be displayed after pressing
START key. Warning sound is also emitted.
q The instrument will exchange L and N terminals automatically if N/L2 and L/L1
test leads (Universal test cable) are connected reversed way or terminals on
tested wall plug are reversed.
q If test result is out of display range “>1999 Ω” message will be displayed!
q Specified accuracy of tested parameters is valid only if mains voltage is stabile
during the measurement!
q “bat” message displayed during or after finishing the measurement means
batteries are too weak to guarantee correct result. Replace the batteries.

Measurements on electric installations in theory and practice.
How to carry out the measurement
Step 1
q Connect test cable (Universal test cable) to EasiTest.
q Set function switch to LOOP L-N, PSC position, L–N(L) voltage measurement
will start to run; see the figure below (left side):
