7.4.1.
RH and T Adjustment and Calibration for Types T5 / T9 / T10
PLEASE NOTE
Before.adjusting.or.calibrating.an.HTS801.with.CG.option.(types.T5 / T9 / T10),.the.CG.function.must.be.
deactivated..Otherwise,.the.heating.may.start.during.adjustment/calibration.and.the.outputs.may.freeze..
The CG function can be deactivated either via PCS10 or the optional display.
PLEASE NOTE
Remember.to.reactivate.the.CG.function.after.adjustment/calibration.to.ensure.proper.functioning.of.the.unit.
7.4.2.
RH and T Adjustment and Calibration for Type T7
The HTS801 with probe type T7 has a dual heating system in a single probe design to prevent both: condensation
on the RH sensing element and on the probe body through a regulated heating strategy. This results in a very
short response time and allows accurate measurement of the dew point temperature Td.
PLEASE NOTE
Before adjusting or calibrating an HTS801 with remote type T7, the probe heating must be deactivated.
Otherwise,.the.probe.heating.will.affect.the.stability.of.the.adjustment/calibration..
The probe heating can be deactivated either via PCS10 or the optional display.
PLEASE NOTE
RH.adjustment/.calibration.of.an.HTS801.with.remote.sensor.T7.is.only.possible.up.to.a.maximum.value.of.
70 %RH. This is due to the controlled heating strategy.
PLEASE NOTE
Remember.to.reactivate.the.probe.heating.after.adjustment/calibration.to.ensure.proper.functioning.of.the.
unit.
7.4.3.
RH and T Adjustment and Calibration for Types T17 / T28
The.HTS801.with.T17 / T28.probes.has.a.dual.heating.system.with.two.probes.to.prevent.condensation.on.both.
the RH sensing element and the probe body through a controlled heating strategy. This results in a very short
response time and fast recovery after condensation. In addition, it enables accurate measurement of relative
humidity even in continuously high humidity and condensing conditions.
PLEASE NOTE
Before.adjusting.or.calibrating.an.HTS801.with.remote.type.T17 / T28,.the.probe.heating.must.be.
deactivated..Otherwise,.the.probe.heating.will.affect.the.stability.of.the.adjustment / calibration..
The probe heating can be deactivated either via PCS10 or the optional display.
PLEASE NOTE
When.RH.adjusting / calibrating.an.HTS801.with.remote.probe.T17 / T28,.it.is.of.utmost.importance.to.keep.
the RH and T probes at the same temperature. This can be achieved for example with the Humor 20 adapter
for T17 models HA020401. Please refer to Humor20 for further details.
PLEASE NOTE
The best adjustment results are achieved when a T adjustment is made first, followed by an RH adjustment.
PLEASE NOTE
Remember.to.reactivate.the.probe.heating.after.adjustment / calibration.to.ensure.proper.
functioning of the unit.
