Calibration
Since electronic balances are affected by gravitational acceleration, they produce different values in various locations.
Therefore, before use, balances must be calibrated at the location where they are installed. Calibration is also required after
long periods without use, or if a balance begins to produce inaccurate values.
Calibration of a balance, or span adjustment, is required to produce accurate measurements.
4.1 Calibration of TP Series
Span adjustment should be performed with the balance installed perfectly level and without any load on the
measurement pan.
1. Press and hold down
.
2. Release the key when the display changes from [
] to [
]
3. Press
while holding down
, then release both keys simultaneously. The display flashes [
],
indicating that zero-point calibration is underway. Zero-point calibration is finished when the display changes to [
]. Proceed to the calibration of the capacity point.
4. Load the calibration weight in the center of the balance. The display flashes, indicating that capacity point calibration
is in progress. When the calibration of the capacity point is finished, the original measurement mode is restored.
Key Points of the Procedure
1. Pressing
in step 2 interrupts the span adjustment and returns to the original measurement mode.
2. The calibration weight used for span adjustment should be heavier than half the capacity of the balance. To
implement a calibration as precisely as possible, use a weight close to the capacity of the balance.
Calibration weights can be ordered from Rice Lake Weighing Systems.
3. If problems arise during span adjustments, one or more of the following error messages will appear.
• [
] - The calibration weight exceeds the capacity of the balance.
• [
] - The calibration weight is less than half the capacity of the balance.
• [
] - The difference between before and after calibration values is too large (1.0% or more).
If error messages are displayed, calibration cannot take place. Check the weight and re-calibrate. If the same
error continues after repeated calibrations using the correct weight, please contact Rice Lake Weighing
Systems.
