Switch function 3, two-point
If the upper limit value LV1 has been exceeded, the output relay LV1
switches. If the value falls below the lower limit value LV2, the output
relay LV1 drops out again. The output relay LV2 switches according
to the programmed switch function.
The function 3 is only possible if different values are used for the limit
values LV1 and LV2 with just one measuring point. For example, for
LV1 = 2 mg/l and for LV2 = 1 mg/l.
Switch function 4, Duration/inverse
If the measured value falls below the limit value LV1 or LV2, the
output relay LV1 or LV2 reacts. If the limit value LV1 or LV2 has been
exceeded, the relevant relay drops out again.

Switch function 5, range LV1-LV2
Monitoring the range between limit values LV1 and LV2. If limit value
LV1 is exceeded, relay LV1 switches and LED "LV1" illuminates red.
If limit value LV2 is not achieved, relay LV2 switches and LED "LV2"
lights up red. If the measured value is within the range, both relays
are deactivated and both LEDs illuminate green.
If this function has been selected, the setting in the menu item
is ineffective.
FUNCTION LV2
Measuring points
®
The Testomat 2000
PO4 can be used for monitoring 2 measuring
points. Measuring point switch-over can occur either automatically or
by triggering a contact (or normally closed) at input IN1. If the
external measuring point switch-over has been programmed ("
measuring points externally
has to be connected to IN1 (volt-free contact required!). The active
status of IN1 has to be programmed accordingly.
