PAXH SPECIFICATIONS
INPUT RANGES:
Isolation To Option Card Commons and User Input Commons: 125 Vrms
Isolation To AC Power Terminals: 250 Vrms *Conditions for accuracy specification:
- 20 minutes warmup
- 18-28°C temperature range, 10-75% RH non-condensing
- 50 Hz - 400 Hz sine wave input with 1.414 crest factor
- 1% to 100% of range
For conditions outside the above listed:
Temperature from 0-18 and 28-50°C: Add 0.1% reading + 20 counts error
Crest factors:
1-3: Add 0.2% reading + 10 counts error
3-5: Add 1% reading
DC component: Add 0.5% reading + 10 counts
20-50 Hz and 400-10 KHz: Add 1% reading + 20 counts error
** Non-repetitive surge rating: 15 A for 5 seconds
*** Inputs are direct coupled to the input divider and shunts. Input signals with
high DC component levels may reduce the usable range.

* After 20 minute warm-up. Accuracy is specified in two ways: Accuracy over an 18
to 28 °C and 10 to 75% RH environment; and accuracy over a 0 to 50 °C and 0 to
85% RH (non-condensing environment). Accuracy over the 0 to 50 °C range
includes the temperature coefficient effect of the meter.
