CAUTION!
Never connect 110 VAC or 220 VAC to rear power
terminals. High voltage AC will damage instrument and
void warranty.

Technical Notes:
•
To reduce the possibility of noise interference, isolate AC
power lines from signal lines.
•
Maximum 4-20 mA loop impedance is affected by the supply
voltage.

Technical Notes:
•
Use three conductor shielded cable for cable extensions up to
30 m (100 ft) max.
•
Cable shield MUST be maintained through cable splice.
Technical Notes:
** 1/8A fuse recommended (customer supplied)

4-20 mA output is internally powered (non-isolated),
maximum loop impedance 350 Ω with a 12 V instrument
supply voltage, 950 Ω with a 24 V instrument supply voltage.
To isolate output and prevent ground loop problems:
1. Use monitor device with isolated inputs, or
2. Use separate DC supply for 5900 and monitor device, or
3. Power 5900 with 12 - 24 VAC step down transformer

System calibration will reduce errors which may be caused by sensor wire lengths longer than the standard 15 foot length. Wire lengths of 100 feet are acceptable; cable shield must be maintained through cable splice.
