Operation Instructions
Figure 2: Current clamps A 1588 - connection to the measuring instrument
Step 1
Connect A 1588 current clamps output connector to the appropriate (Metrel Power series)
measuring instrument’s current input terminal
.(See figure 2)
!
Do not connect clamp output elsewhere than to Metrel PQ series of measuring
instruments (Energy Master MI 2883, Master Q4 MI 2885 and Power Master MI 2892)!
Step 2
Switch on the measuring instrument. Set Smart clamps and range
on instrument’s measuring
setup.
(For further information see Instruction manual of measuring instrument.)
Step 3
Clamp the probe around the current-carrying conductor(s) to be measured. Make sure that
probe jaws are tightly closed around the conductor(s).
!
Do not extend hands over safety barrier to prevent of electric shock! Only handles
are allowed to be touched during measurement!
!
Do not use the current clamp if any damage is noticed!
!
Consider all generally known precautions in order to avoid risk of electric shock
while dealing with electric installations!
