4.1 Description

Universally applicable hand-held thermometers for demanding, mobile temperature measurement, distinguished by flexibility and easy handling. In addition to Pt100 resistance thermometers, they can also process signals from typical thermocouples. Thus temperatures from -200 ... +1,500 °C (-392 ... +2,732 °F) can be measured.

Low-drift measuring amplifiers ensure small measurement errors, while easy-to-use adjustment features considerably simplify adjustments and calibrations:

■

Calibration by code for fast setting of standard probes via key data

■

Physical calibration of probe and display at one, two or three different temperatures In this way it is possible to reduce measuring errors to a minimum and ensure a high indication accuracy.

Hand-held thermometer, model CTH6300, industrial version

Its design makes the CTH6300 especially suitable for the commissioning, maintenance and service/calibration of temperature instruments and equipment.

Hand-held thermometer, model CTH6500, precision version

Due to its high accuracy of 0.03 K in the range from -100 ... +150 °C (-148 ... +302 °F), the CTH6500 can be used as a reference instrument in the biotechnology, pharmaceutical and food industries. The CTH6500 is thus ideal for all service and maintenance tasks.

4.5 Voltage supply

The battery life is approx. 20 hours for continuous operation.

The BAT segment indicates that the battery must be replaced soon. From this point,

correct measurements can be performed for approx. 1 hour. A 9 V battery is used as

voltage supply of the instrument. For information on the battery see chapter 4.6 “Battery

replacement”.

4.6 Battery replacement

For battery replacement switch off the instrument and open the battery compartment

attached on the rear side. After that remove the battery and disconnect the connection

cable. Then insert the new batteries into the battery compartment.

Switch in the battery compartment on the rear side allows to specify whether the

instrument is operated with a battery or a rechargeable battery.

■

With the setting Batt, the charging current supplied via USB interface is not directed to the battery, so that this does not damage it.

■

With the setting Accu, the rechargeable battery is charged only via the USB interface. While the rechargeable battery is supplied with a charging current, this is not, however, enough to charge the battery fully.

If the instrument is not used for a long time, remove the battery. When closing the battery compartment make sure that the battery connection wires are not jammed or damaged.

6.4.4 Calibration mode CAL

This measuring instrument offers the possibility to perform a simple calibration when replacing the probes in order to compensate the manufacturer-specific tolerances of the probes and guarantee a consistently high accuracy for your measuring chain.

The instrument has 3 different calibration modes:

[OFF]: Standard characteristic curve

for example, for Pt100 resistance measurements DIN IEC 60751

oP1: Calibration by code

The 2 x 4-digit code, clearly and visibly displayed on the handles of our probes, corresponds to a 2-point calibration

oP2: Physical calibration

Calibration with reference standards: 1-point, 2-point or 3-point calibration possible

6.4.4.1 Calibration function combined probe (humidity/temperature), CAL

All humidity probes by WIKA are combined probes. This means that besides the humidity sensor they also contain a temperature sensor. Both measurement parameters are connected to the same measuring channel using one

probe connector. To calibrate both measurement parameters, humidity and temperature, the measurement parameter rH (rel. humidity) must first be set (see chapter 6.4.2 “Probe selection Prob”).

The instrument has 3 different calibration modes:

OFF Standard characteristic curve

no probe-specific correction is performed

oP1 Calibration by code

The 2 x 4-digit code, clearly and visibly displayed on the handles of our probes (rH = humidity and P °C = temperature), corresponds to a 2-point calibration

oP2 Physical calibration

Calibration with reference standards: 1-point, 2-point or 3-point calibration is only possible for the measurement parameter rH humidity.

CAL = calibrate
