4.2 Basic Color Measurement
The TES-135A measures color difference between a target sample and a reference sample.
- Calibration: Before first use or after prolonged storage, perform a white calibration. Place the meter's sensor firmly against the standard white plate (usually included) and press the CAL button.
- Set Reference: Place the meter's sensor firmly against your reference sample. Press the T (Target) button to store this as the reference color. The display will indicate that the target color has been set.
- Measure Sample: Place the meter's sensor firmly against the sample you wish to compare. Press the R (Read) button.
- View Results: The display will show the color difference values (e.g., ΔL*, Δa*, Δb*) between the sample and the reference.
The device supports various color difference and color space displays:
- Color difference: Δ(L*,a*,b*), Δ(E*ab,C*ab, H*ab), Δ(Y, x, y), Δ(X, Y, Z) or Δ(Rs, Gs, Bs)
- Color space: (L*, a*, b*), (L*, C*ab, hab), (Y, x, y), (X, Y, Z) or (Rs, Gs, Bs)
Refer to the on-screen menu or specific buttons (if available) to cycle through these display modes.
4.3 Advanced Functions
- Maximum, Minimum, and Average Function: Press the MAX/MIN/AVG button (or similar) to cycle through these statistical values for a series of measurements.
- Tolerance Function: Activate the tolerance function to set acceptable color difference limits. The device will indicate if a measured sample falls within or outside these limits (e.g., PASS/FAIL). Consult the manual for specific button presses to set tolerance values.
- Auto Memory (99 sets) & Read Function: The device automatically stores up to 99 sets of measurement data. Use the MEM or READ buttons to recall stored data.
- Target Color Memory (8 channels): The device can store 8 different target colors. These can be set by measurement or manually entered via the keypad (if available).
