Recalibrate LOPT
Recalibrate HIPT
The capacitance is too much , please select plastic coating version,
or caused to short between probe and wall.
The output is latched , enter CTRL LACH to turn off this function
The output range is smaller than 20Pf, Adjust range to low level and recalibrate it
There is shortcut between probe and tank wall, please recheck the installation
Increase "DAMP"value
Set "FILT" to HI ,increase the frequence of filter
1. Enter manu"CAP" to check if the value change
2.When level remains , but the value change <1pF , please recalibrate HIPT &LOPT
3.When level remains, but the value change >1pF , please recheck the wiring.
Enter the manu to E_4, If the display at the control room >
, decrease
E_4 value ;if the display at the control room< low point , increase E_4 value
low point
Enter the manu to E_20, If the display at the control room >
, decrease
E_20 value ;if the display at the control room<high point, increase E_20 value
high point
Remark 1: Please refer to calibration procedure for HIPT & LOPT setting.
Remark 2:
Remark 3:
Remark 4:
The output is latched when display is up to 110% or -10%
Re-calibration is essential when the measuring range is revised.
When calibrating 4 .20mA, 0.24uA per step will be changed
when press up bottom once.

Description
1. Button Protection, requiring to press ENT+UP
buttons for 2 seconds in order to get into main menu.
2. Three input buttons; user-friendly.
3. Any two points for calibration
4. Retention for maximum and minimum values.
Low point Capacity Value
When the probe is surrounding by the air , little capacitance
(C ) is measured by the equivalent capacitor , the
A
capacitance increase gradually as computing media, the
max. capacitance (C ) will be measured while the tank is
B
full, the difference (dC)between C and C is proportional to
A
B
the level.
