-On Monex click the 'Get Prod Info' Tab, in the Model ID you should read AC Monitor
+On Monex click the 'Get Prod Info' Tab, in the Model ID you should read 'AC Monitor'
 Now go to the AC Monitor Tab, you should see:
-=== Step 12 ===
+{{:internal:proddocs:ac_monitor_tab_monex.png?500|}}
-Turn on the Variac Power, the Blue LCD display on it should state the voltage. Turn the Dial to output 25V.
+=== Step 13 ===
+On the AC Monitor Tab:
+Change Set Parameter to 'Circuit Type'
+Change Circuit Type to 'Three Phase'
+{{:internal:proddocs:change_phase.png?300|}}
+Click 'Send'
+All Phases should stop being unavailable and say '0', the frequency should say 49.9.

+=== Step 14 ===
+**MAKE SURE ALL CONNECTIONS ARE ACCURATE BEFORE TURNING POWER ON (Step 2 - Step 5 otherwise you could potentially damage the PCB)**
+Turn on the Variac Power, the Blue LCD display on it should state the voltage.
+Turn the Dial to output 25V.
