Carrying Out Measurements - Magontec CorroScout 500 Instrucciones De Uso

4. Carrying out measurements

4.1 Testing the mains voltage supply for CORREX
This measuring function can be used when the light emitting diode(s)
of the CORREX
a lack of mains voltage is suspected.
Proceed as follows to test the mains voltage.
1. Set the rotary switch of the CorroScout
range (230 V) of the "Netz" (Mains) group.
2. Connect the measuring clips with the mains supply (clamps in the
switchbox, lead ends). The instantaneous measuring value is
shown on the display. The measuring range 115 V AC can be
selected for mains voltages 115 V AC.
Warning: Never exceed the maximum admissible input of 300 V; do
not test 380 V connections! Do not touch any circuits or circuit ele-
ments. Risk of electric shocks!
4.2 Testing the protective current between anode and tank
Safety instruction: Before carrying out this measurement, discon-
nect the electric tubular heater from the mains.
This function will test the current flow and intensity between anode
and tank. No electric current will flow in the case of depleted Mg
sacrificial anodes. Incorrectly electrically insulated, non-enamelled
heat exchangers as well as large surfaces of enamel failure usually
result in increased protective current demand.
Information: Non-insulated, for instance, with locknut welded Mg
sacrificial anodes cannot be tested with CorroScout
circuit "Anode against tank" cannot be opened to the measuring
device.
Proceed as follows for testing the protective current of built-in Mg
sacrificial anodes:
1. Disconnect one of the two sides of the (black) connecting lead
between the insulated installed Mg anode and the tank.
2. Set CorroScout
setting, first to the highest possible measuring range (200 mA).
