BEvT
Battery Evaluation Time
Time in seconds the tool averages battery voltage for evaluation purposes.
10 seconds
BThr
Low Battery Threshold
The voltage threshold below which the tool will alert the operator or switch to battery 2. LoVWthr in XXT
23 volts
CMTF
Correct for Magnetic TFA Declination
Enables or disables the correction for magnetic declination at surface or down hole.
Surface
DiAA
Auto Data Acquisition Control
Allows putting the directional data acquisition process in automatic data mode for test purposes.
Off
DipT
Dip Angle Tolerance
.60 degrees
DwnL
Downlink commands
Enables or disables the Downlink capabilities of the system.
Disable
EvIM
Evaluation Mode
Tells the tool to derive the inclination during the survey sequence only, or during both the survey and toolface/logging sequence.
Survey
FDM
Flow Detection Method
Switch
FEvT
Flow Evaluation Time
How long the flow input must indicate a state change before the system will respond to the change. Stored in the tool. Must be the same as PEvT.
5 seconds
GrvT
Gravity Magnitude Tolerance
.006
Gsf
Gamma Scale Factor
Multiplier which is applied to gamma counts.
1
GSPC
Gamma Sensor Power Control
When enabled, the sensor is powered only during flow conditions. Always set to enable.
Enable
HdCK
Type of Header Check Bits
The method used to confirm the accuracy of received data.
Parity
HiPL
High pulse Amplitude Limit
Pulses higher than this limit will not be reported or processed. Set to a value higher than the pulse amplitude. The ratio of HiPL:LoPL is typically set to approximately 10:1, but can be adjusted as needed.
300 PSI
IncT
Inclination Threshold
The inclination at which the tool will switch from magnetic to gravity tool faces.
5 degrees
InvF
Invert Flow Sense
Off
Loc
Jobsite Location
Enter the well name.
From well plan
LoPL
Low Pulse Amplitude Limit
Pulses lower than this limit will not be reported or processed.
30 PSI
MagT
Magnetic Field Tolerance
.005
MDec
Magnetic Declination
degrees
ModN
Mode Number
Determines which of the four different modes the tool will use.
1
NDip
Nominal Dip Angle
From Well Plan
NGrv
Nominal Gravity
1.000 G
NMag
Nominal Magnetic Field Strength
From well plan
NSyP
Number of Sync Pulses
Number of single wide pulses in a sync word.
4, 3 in benchtree
PALMode
Pulse Amplitude Limit Mode
When manual, the system uses the defined LoPL and HiPL. When auto, the system calculates the LoPL and HiPL.
Auto in XXT, not available in benchtree.
PEvT
Pumps On/Off Evaluation Time
How long the pumps input must indicate a state change before the system will respond to the change. Must be the same as FEvT.
5 seconds
PmpT
Pumps On Threshold
The pressure threshold above which the receiver considers the pump to be on. The setting for this variable depends on the expected pressure.
500 PSI
PTfs
Pressure Transducer Rating
The nominal pressure rating for the pressure transducer. Usually set to 10000 PSI
PTG
Pressure Transducer Gain
A multiplier used to increase pressure readings.
1
PTO
Pressure Transducer Offset
0
PWTmg
Type of Pulse Width Timing
Use narrow when the signal noise ratio decreases and there is a low level of pulse distortion. Use wide when pulses become distorted and are being rejected.
Normal
RxDT
Receiver Delay Time
The time delay required from pumps on until the receiver begins looking for signals from the tool.
45 sec
RxFBwF
Filter Bandwith Factor
1
SHSz
Survey Header Size
The number of bits in a survey header.
3
SuAM
Survey Acquisition Mode
Tells the tool whether to acquire survey data during the "Flow" or "No Flow" state.
No Flow
SuDT
Survey Acquisition Delay Time
Delay time from a "No Flow" state until the data acquisition process occurs.
25 sec
SyTy
Sync Word Type/Format
The type of Sync word generated by the tool.
1111
SyWF
Sync Window Factor
The amount of time that the receiver will look for sync pulses, before indicating that it missed sync. A value of zero indicates an infinite sync window.
0
THSz
Toolface/Logging Header Size
The number of bits in a toolface/logging header.
3
TLTx
Toolface/Logging Transmission Time Limit Control
In mode 1,2,3 or 4. Tells the tool how long, in minutes, to transmit toolface/logging data. A value of zero means the tool will continue to transmit data until pumps off.
0
TmpT
High Temperature Threshold
125
TxDT
Transmit Delay Time
The time delay required from "Flow On" until the tool begins to transmit signals
60 sec
