Safety Zone Alarm Reset (SZ Alarm Reset)
Clears a latched Safety Zone Fault. (User password)
Threshold (Threshld)
Select threshold type. (User password)
Only select FIXED in applications with low dielectric material over higher dielectric
material where device is reading incorrect level (for example, oil over water.)
In FIXED mode, the device captures the first valid return signal and should be used in
water bottom applications or with bulk solids probes with stainless steel weights.
Interface Threshold (Ifc Threshld)
Applicable only when Ifc, Ifc&Vol selected. Select threshold type for interface level pulse.
(User password)
For interface mode only. Threshold for interface pulse levels. Set to CFD for most common
applications.
Poll Address (Poll Adr)
Enter HART polling address number. (User password)
Trim Level (Trim Lvl)
Enter value to adjust level reading. Used to adjust for mounting/installation effects with
single rod probes. (User password)
Trim 4 mA (Trim 4)
Adjust setting to output exactly 4.0 mA. (User password)
Attach a current meter into the loop. Adjust the trim until the meter reads 4.00 mA. The
value of Trim mA is typically 651 counts, but will vary from unit to unit by about ±25 counts.
Trim 20 mA (Trim 20)
Adjust setting to output exactly 20.0 mA. (User password)
