CR87HT High Temperature Recorder
The CR87HT is a precision instrument used to monitor and record temperature
on a 6" circular chart. The CR87HT may be carried as a portable instrument or
mounted in a fixed location.
The CR87HT offers a variety of features to meet any temperature recording requirements. A combination of three temperature ranges and four chart speeds
provide a high degree of flexibility. I
single or continuous turn operation as required by a particular application. To
protect the data being recorded, the CR87HT uses an automatic battery backup
to maintain operation during a power outage.
n addition, the chart rotation may be set for
CR87HT FEATURES AND CONTROLS
1. The 3 DIGIT TEMPERATURE DISPLAY provides precision temperature
reading of the environment monitored by the thermocouple sensor. When
the CR87HT is operating on battery power, the display will flash on once
every several seconds to indicate battery operation and to conserve battery
power. When the batteries are nearly discharged, the display will alternate
the display reading and "LO" to advise the operator that the batteries are
discharged and the CR87HT will shortly cease operation.
NOTE: The battery back
use in situations where primary power is lost for short periods of up to 48
hours. The CR87HT is not intended to be used as a battery powered instrument. If the CR87HT is to be stored for an extended period, it is strongly advised to disconnect the battery pack and remove the batteries to avoid
damage to the instrument from battery leakage.
2. The TEMPERATURE RANGE SELECTOR allows the user to choose the
desired temperature range for measurement and recording.
3. The CH
one full chart revolution. The corresponding chart has to be chosen according to the desired chart speed and temperature scale. Chart part numbers are listed in this manual.
4. PEN POSITION ADJUSTMENT KNOB allows the user to adjust the position
of the chart pen to match that of the digital display. Usually, this adjustment
will be required after replacing the chart pen.
5. CHART ADVANCE BUTTON is used to set the chart to the correct time.
Press and hold the Chart Advance button until the desired time lines up with
the Time Pointer (I
Movement of the Chart Spindle (Item 9) by hand can cause permanent
damage to the chart mechanism.
ART SPEED SELECTOR allows the user to select recording time of

6. TEMPERATURE ADJUSTMENT feature allows the user to adjust the digital
display during periodic calibration and certification. The CR87HT has been
factory calibrated and requires no adjustment to meet all published specifications.

WER ON/OFF / CONTINUOUS / SINGLE CHART SELECTOR allows
the user to apply power to the CR87HT and to select Continuous or Single
Turn for the chart rotation. When power is first applied to the CR87HT, the
display will show "888" to test each segment of the display, and the pen will
move to the edge of the chart. The display will then show the temperature at
the thermocouple sensor and the pen will move to the correct position on
the chart. If the chart range does not match the temperature at the thermocouple sensor the pen will move to the upper or lower range of the chart,
whichever is closest to the temperature at the sensor, and stay there until
the correct chart range is selected or the temperature at the thermocouple
sensor moves within the range of the chart being used. In the Continuous
switch position, the chart will rotate until power is removed. In the Single
Turn switch position, the chart will make one complete revolution and stop.
A blinking dot (Item 1) will indicate that the chart has made one complete
revolution and stopped. To reset the chart for another revolution, place
the switch in the Continuous switch position until the blinking dot goes out
and then slide the switch back to the Single Turn position. The chart will
make one complete revolution and stop.
observe this will cause the pen to read incorrectly and may result in damage
to the pen mechanism.
. The pen has a wrap-around arm
latch which makes the pen replacement "A SNAP!" To replace the pen, gently
lift up the PEN ARM, (do not over bend pen arm) release the pen latch by
pushing it down, and remove the pen; place a new pen on top of the pen arm,
align the notches on the pen arm with the notches on the pen latch and close
the latch by wrapping it around the pen holder until it is secured. Replace cap
on the pen tip when the CR87HT is not used to insure long pen life. For pen
installation see Fig. I

THE INTERNAL MECHANISM.

able from any of Sealed Unit Parts Co., Inc. authorized distributors in a box
of 60 charts each. The chart part numbers are listed in manual.
TO INSTALL A NEW CHART disconnect power from the CR87HT by se-
lecting OFF with the Power/Single/Continuous Chart Selector. Place pen
cap on point. Gently lift the pen arm, and while holding it, remove the old
chart. Slide a new chart under the pen holder and align the chart with the

chart spindle. Apply power to the CR87HT and rotate the chart by depressing the chart advance button until the time pointer is aligned with the line on
the chart representing the right time of day. Remove pen cap. If necessary,
adjust the pen position according to the front panel display reading (see
PEN POSITION ADJUSTMENT KNOB Item 4).
11. The TIME POINTER is simply a point against which the current time is being
read during a chart rotation. I
nitially a new chart has to be rotated until the
time pointer shows the right time and day when using a 7 day chart.
12. The HANDLE for carrying, folds towards the back of the case to be out of
the way when CR87HT is mounted on the panel or on the wall.
13. KEYHOLE SLOTS located on the back of the case are provided for wall or
panel mounting.
14. The REAR COMPARTMENT was designed to store the battery holder for
battery back
up as well as the connection for the adapter box.
15. The THERMOCOUPLE SENSOR is interchangeable. The furnished sensor
has 15 feet of cable. The sensor is a type J thermocouple and uses the industry standard connector for thermocouple sensors. Different sensors from
third party manufacturers may be used, but Supco can not be responsible
for the quality or accuracy of any sensor not manufactured by Supco.
The recorder should be placed outside the chamber being monitored. DO
NOT PLACE THE RECORDER DIRECTLY IN AREAS OF EXTREME
TEMPERATURES, H
IGH HUMIDITY OR HEAVY CHEMICALS.
16. The BATTERY HOLDER is stored in the rear compartment for backup batteries. Use of alkaline "AA" batteries is required for proper operation.
17. 12VDC WALL TRANSFORMER provides primary power for the CR87HT.
Alternate sources of 12 Volt power may also be used. This allows use of the
CR87HT in automotive, marine or other mobile applications.
18. The POWER CONNECTOR is a connection jack
for the 12VDC wall trans-
former or alternate source of 12VDC power.
19. Snap on EXTRA SUPPORT LEGS for better stability.
