[VIDEO]: Configuring CT Ratio using the WattsOn-Mark II built-in Display
The following video tutorial outlines how to set the CT Ratio / Turns Ratio on a WattsOn-Mark II meter with the onboard LCD display (-DL option)
Note: mA meters have a field for only the "CT Turns", so there is no ratio per se (ie: there is only one number, you will not see the ":1" field)
CT Ratios for Elkor's Common CTs are as follows:
mA CTs (for use with -mA meters)
| Model | Turns Ratio |
| MCTA | 2500:1 |
| MCTB | 4000:1 |
| MS160 | 3000:1 |
| MS240, MS360 | 2000:1 |
| MSCT1, 2, 3 | 7500:1 |
| MRA-75, 125, 2x3 | 7500:1 |
| MRA-3x5 | 15000:1 |
5A CTs (for use with -5A meters)
| Model | Turns Ratio |
| nnn:5A | nnn:5 |
mV CTs (for use with -mV meters)
| Model | Turns Ratio |
| nnn:333mV | nnn:333 |
Rogowski Coil (for use with -RC meters)
| Model | Turns Ratio |
| RC-600 (60Hz) | 1000:120 |
| RC-600 (50Hz) | 1000:100 |
| RC-400 (60Hz) | 1000:120 |
| RC-400 (50Hz) | 1000:100 |
