phase or for the simulation of a steep
temp-gard curve. The maximum
power consumption is 3,400 watt
(VA).
Power Consumption - The oven
requires 15 A maximum during the
heat-up phase or when simulating a
steep temp-gard curve.
Power Supply - The power supply must
be 230 V ± 10 %, 50 or 60 Hz. The
oven is equipped internally with a 5 V
d.c.-voltage component supplying the
CPU and a DC-DC converter (5 V ±
15 V) supplying the AD converter.
Preheating Zone - Modern waterborne
paints require a suitable pre-heating
time prior to baking. During this
period the temperature should not
exceed 80°C (craters resulting from
vapor bubbles). Only after all of the
water has evaporated the coating is
exposed to its baking temperature.
This can be tested under 'Double
Macros' which allows two gradients to
be combined.
Pressing Device - Mechanical device
that holds the test panels. The
pressing device is fitted with
insulating plates made from mica.
The cover, made of perforated
aluminum plate, prevents air
circulation above the test surface. It
exerts a pressure of approx. 16 kp.
which is evenly distributed over the
entire length of the test panel by the
insulating plates.
Printer - The flat bed printer, Cat. No.
2630, can only be connected to
gradient-ovens Cat. No. 2601 - 2610.
Selecting 'Printer on/off' under
SETUP Menu' allows the printer to
print a report after each test as
required. With the keys 'P' (= print
report) and 'L' (= label), a report or
label can be printed out at any point
in the baking process.
Printer Paper - Precut self-adhesive
strips, Cat. No. 2636, for reports, or
Cat. No. 2637, for panel marking
strips (labels) should be used. For
reports, normal typewriting paper can
also be used.
PRINT Key - The 'P' key is used to print
out reports during the baking process.
Press the PRINT key to receive a
detailed report from the connected
printer.
Pt-100 - Pt-100 is a platinum resistor
possessing exactly 100
at 0 °C. The classification of the
Pt-100 sensors used in the gradient-
oven is in accordance with DIN
(German Industrial Standards).
Pt-100 Measurement - All internal
measurements taken, either of the
heating bank or the electronics, are
executed by the Pt-100 sensors.
References - See our separate
'Reference List'.
Reflow Behaviour - This means e.g.
the reflow of automotive paints which
after having been marred by grinding
or repair work were baked again.
With the gradient-oven the reflow or
thermoplastic behaviour can be
tested quickly and economically.
Repetitive Test - Because of the simple
programming and excellent
reproducibility of the gradient-oven, a
repetitive test can be conducted
easily. Precision is determined by the
tolerances given in the technical data
sheet.
