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 re-

quirements. A combination of three temperature ranges and four chart speeds

provide a high degree of flexibility. In addition, the chart rotation may be set for

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.

ONTROLS

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 backup feature of the CR87HT is primarily intended for

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 instru-

ment. If the CR87HT is to be stored for an extended period, it is strongly ad-

vised to disconnect the battery pack and remove the batteries to avoid

damage to the instrument from battery leakage.

2.   Th

TEMPERATURE RANGE SELECTOR 

allows the user to choose the

desired temperature range for measurement and recording.

3.   Th

CHART SPEED SELECTOR 

allows the user to select recording time of

one full chart revolution. The corresponding chart has to be chosen ac-

cording to the desired chart speed and temperature scale. Chart part num-

bers 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 (Item 11).The chart is rotated counterclockwise only.

Movement of the Chart Spindle (Item 9) by hand can cause permanent

damage to the chart mechanism.
