AHIBA MULTIPRECISE TC - Calibration (Dosing)
General Instruction:
- The dosing accuracy of fluids is dependent on the type of chemicals as well as
thier stock solution concentration (specific gravity).
- The Ahiba MPTC is calibrated with water at the factory. It is required for the
operator to recalibrate the unit with the chemical to be used.
- By means of calibration, the exact quantity can be dosed (varying specific
gravities can therefore be calibrated out).
Equipment needed:
Measuring cylinder (graduated beaker).
Recommeneded beaker size is 50ml for better accuracy.
1. CALIBRATE
a. Ensure tube is primed with water. If not go to [ CONFIGURATION ], [ DOSAGE ],
[ PRIME TUBE ].
b. Fill graduated beaker with 50ml of water and insert dosing tube into the beaker.
c. Go to [
CONFIGURATION ], [ DOSAGE ], [ CALIBRATE ], press [Enter] key.
d. When finished record the volume dosed (Volume dosed = 50ml - remaining
volume in the beaker).
e. Repeat and calculate the average value. Enter the average value in
“MEASURED XX.Xml” and press [Enter ] key.
f. Press [Esc] to exit and then [Enter] key to save value.
2. DOSING VERIFICATION
a. Fill graduated beaker with with 50ml of water and insert dosing tube in the
beaker.
b. Go to [ CONFIGURATION ], [ DOSAGE ], [ DOS VERIFICATION ], enter 10ml and
press [Enter].
c. Verify that the dose amount is 10ml ±0.5ml, increase the “MEASURED XX.Xml”
by 0.3 in step d. Decrease the value if the opposite is true. Verify again until the
dose volume is within tolerance.
The tolerance is XXml ±0.5ml or XX ±2%
