1529 Chub-E4 Thermometer Readout
User’s Guide
4.4.1Using the Clamp-on Ferrites
Clamp-on ferrites are provided with this product for the use of improving its
electromagnetic (EM) immunity in environments of excessive EM interference.
During EMC testing we found that ferrites clamped around the probe cables
and power cord reduced the risk that EM interference affects measurements.
Therefore, we recommend that the clamp-on ferrites provided (Steward P/N
28A2025-0A2) be used on the cables of probes attached to this product, espe
cially if it the product is used near sources of EM interference such as heavy in
dustrial equipment.
To attach a ferrite to a probe cable, make a loop in the cable near the connector
and clamp the ferrite around half of the loop as shown in Figure 1. The ferrite
can be easily snapped open and moved to a new probe when needed.

4.5Connect the Power Source
The 1529 draws power from either a 15-volt DC power supply (the included
AC adapter) connected to the DC input or the internal re-chargeable battery
pack. To use the AC adapter, plug it into a wall outlet of the appropriate voltage
and insert the DC plug into the DC power input of the 1529 (see Figure 3 on
page 18.)
4.6Switch the Power On
Power is turned on and off with the power switch located on the top right cor
ner of the back panel. To switch the power on, toggle the power switch to the
‘ON’ position. To switch power off, toggle the power switch to the ‘OFF’ posi
tion. The instrument takes a few seconds to power up, initialize, and begin nor
mal operation. A self-test is performed displaying the channel configuration
and status of the system, calibration, GPIB, memory, and buttons. If the ther
mometer readout calibration has expired, the user is notified and must press the
-
-
-
-
Enter button to continue initialization. If an error message is displayed on
power up see Section 11.1, Troubleshooting.
4.7Measure Temperature
After initialization, the temperature measurements for the configured channels
are displayed. The appropriate sensor type must be selected and coefficients en
tered for the measurements to be accurate (see Section 7.2.1, Edit Probe). Place
the sensors of the probe into the object(s) you want to measure. DO NOT force
the probe(s) or otherwise allow them to be bent, stressed, or overheated. Probes
can be easily damaged if misused. For further suggestions on handling the
probe and using the 1529 and probe to measure temperature accurately, see

6General Operation
6 General Operation
Display
This section explains basic operation of the 1529 thermometer readout. De
tailed operation of the 1529 is explained in Sections 7 and 8. Section 7 explains
the menu structure and the functions available in the menu structure and Sec
tion 8 explains the communications interface for operating the 1529 remotely.
6.1Display
The 1529 display consists of two parts. The top portion of the display is used
for displaying the measurements from one to four inputs. The bottom portion of
the display is reserved for the programmable fields and field display sets. Infor
mation about the channels and measurements can be displayed in greater detail
such as min, max, spread, standard deviation, and many other functions. When
the measure period is 0.1 or 0.2 seconds (fast measurement mode), the pro
grammable fields and field display set information are not displayed.
6.2Changing Units
The 1529 thermometer readout is capable of displaying temperature in Celsius
(C), Fahrenheit (F), or Kelvin (K). (Displaying in units of Ω,KΩ,ormVisalso
available through the PROBE menu and is channel specific.) Temperature units
are changed on all channels (not individually) by pressing the buttons on the
front panel when not in the menu structure. Press the Unit, LR, buttons to
scroll forward and backward through C, F, or K. All channels or fields that are
displaying temperature on the upper or lower display are updated to the new
units.
-
-
-
-
Channels that are set to Ω,KΩ, or mV in the PROBE menu are left unchanged
when temperature units are modified. Changing the units resets the statistical
calculations (displayed in the bottom portion of the display).
6.3Battery
The 1529 thermometer readout has a built-in nickel-metal-hydride battery pack
that can power the instrument for about eight hours before needing to be re
charged. The battery discharges more quickly when the display backlight is
used. The percent of battery charge remaining is displayed on the bottom por
tion of the display when the battery power is being used. The battery percent
age is approximate and should only be used as a general guideline when
determining the length of charge remaining. The battery is recharged in situ
(while in place) using the AC adapter that is provided.
Plug the AC adapter into the wall outlet and connect the DC plug of the adapter
into the 1529. The battery is charged as necessary whether or not the instru
ment is switched on. The power control circuit inside the instrument manages
battery charging and stops charging the battery automatically when the battery
-

User’s Guide
is fully charged. Only charge the battery when ambient temperature is between
16°C and 30°C (61°F and 86°F) It normally takes about three hours to fully
charge the battery. The instrument can be operated while the battery is being
charged. The charging indicator on the back panel is green when the battery is
fully charged and amber when being charged using the AC adapter.
The battery may self-discharge over several months, especially if the tempera
ture is warm. The battery pack can be used for a minimum of 500 charge-dis
charge cycles before needing to be replaced. Replacement battery packs are
available from the manufacturer. The battery pack can be easily removed and
replaced in the field by following this procedure:
1.Power the 1529 off and unplug the AC adapter from the unit.
2.Turn the 1529 over to expose the battery compartment. Remove the bat
tery cover hex screw. Place the screw in a safe place so it won’t get lost.
Flip open the battery cover to reach the battery pack.
3.Remove the battery pack. Gently disconnect the battery plug connector.
4.Attach the polarized plug of the new battery pack onto the connector.
Note: The battery plug is polarized and can only be plugged in one direction. DO NOT force it. Place the battery pack in the battery
compartment.
5.Close the battery cover and replace the screw. Avoid pinching the battery
wires.
6.Plug in the AC adapter and charge for a minimum of four hours for the
initial charge. Used batteries must be disposed of properly. Check your
local regulations for additional information. You may return used batteries to the manufacturer. Never dispose of batteries in fire as this may result in an explosion with the possibility of personal injury or property
damage.
When the battery charge is not at 100%, the measurement accuracy is not af
fected. If the power is interrupted while the instrument is logging measure
ments (on demand or automatically), the logged data is preserved and logging
resumes when the power is restored.

Each input module supports two channels. Your 1529 thermometer readout is
configured at the factory and is not field changeable. Input modules should
never be removed for any reason.
All possible configurations are shown in Figure 3 on page 18.
6.4.1Connecting a PRT or Thermistor Probe
PRT and thermistor probes are attached to the resistance input module via Hart
Scientific mini-DWF connectors. These patented connectors accept bare wire,
spade, or mini banana plug terminations. The connectors are color coded for
ease in connecting lead-wires.
When using 2- and 3-wire sensors, the accuracy of the 1529 is reduced as
stated in the specifications. Compensation is made for 3-wire PRTs, but the dif
ference in lead resistance affects the measurement accuracy. The 1529 ther
mometer readout is unable to compensate for 2-wire lead resistance.
Attach the lead-wires of the probes as shown in Figure 5 on page 24. The top
termainals sense current and the bottom terminals sense potential.
6.4.2Connecting a Thermocouple
The 1529 thermocouple input module accepts both standard and sub-miniature
size thermocouple connectors. The connection is made with the positive terminal on the right and the negative terminal on the left. You must use a connector
that matches the thermocouple type for the internal RJC to be accurate. For example, if you are using a type K thermocouple you must also use a type K connector, which is made from the same type of metal. For best results, wait two
minutes before measuring after inserting the thermocouple connector into the
input module.
