Line Voltage and Measurements
•
Hot to Neutral.
•
Neutral to Ground.
•
Hot to Ground.
•
Range: 200.0 V RMS.
•
Accuracy: ±5% of range.
Leakage Current
Leakage current is measured through a 1 k
Ω
AAMI load RMS or DC
measured and displayed in microamperes. These tests can be thought of as
measuring the voltage, in millivolts across the same load.
Leakage Current Measurements
•
Case external.
•
Case internal.
•
External.
•
ECG—Leads are RL, RA, LA, LL, and V1-V6 tied together:
1. To ground, all leads or individual leads.
2.
Lead to lead, individual leads to all other leads together.
3. Lead isolation (RMS only), all leads or individual leads.
This test is with line voltage applied from the lead(s) to
ground, current limited by 120 k
Ω
.
Note
If you receive abnormally high leakage current measurements
with V1-V6 leads tied together, you can inspect individual V
leads by removing the other leads. This procedure allows you to
isolate the lead with a high leakage current reading.
