DESCRIPTION
Model PM706 Digital Temperature Meter monitors and
displays temperature measurements using a Type K thermo-
couple input. Meter features dual adjustable set points with 1A
relays and a selectable 4-20 mA or 0-10 VDC output signal.
View alarm settings by depressing the tactile alarm button on
the front panel. The bright red LED display has a floating deci-
mal point and displays temperature in ˚F or ˚C. Meter is
equipped with overrange indication to alert operator of an
open thermocouple or faulty connections. Sealed front panel is
rated to NEMA 12 to protect against dust and fluids.

Installation and Connections
The panel requires a 1.73 x 3.62

Љ (44 x 92mm) panel cut out

with minimum radius corners. Maximum panel thickness of
5/16

Љ (4mm).

Remove the two retaining clamps by loosening and removing
their screws.

Feed the meter housing through the panel and re-fit the
clamps, holding them close to the meter housing as the
screws are tightened.

Tighten the screw sufficiently to retain the meter in the panel.
DO NOT OVER TIGHTEN THE SCREWS, otherwise the
threads in the case will strip.

Ensure the available input power is of the correct level, and is
fused at no more than 0.5A, filtered if on the same leg as heavy
switch gear, and is provided with an adequate clean ground.

Ensure any signal cabling is secured and kept clear of high

PHYSICAL DATA

Signal Input: Type K Thermocouple.
Signal Type: Single ended, negative wire connected to meter com-
mon.
Temperature Range: -148 to 1999˚F (-100 to 1200˚C).
Accuracy: ±2% at 23˚C ambient.
Resolution: 1˚F/˚C.
Read Rate: 2.5 readings/sec.
Setpoints/Alarms: One setpoint active below reading (internally
reconfigurable to above reading) and one setpoint active above
reading. Active condition indicated by LED indication.
Setpoint Adjustment: Set points adjustable by 20 turn poten-
tiometers by removal of front cover. 0 to 2000 counts, adjustable
within 5 counts or better.
Setpoint Hysteresis: 3(0) counts max hysteresis built in to each
setpoint.
Setpoint Viewing: By depression of front panel accessible
switches. Indication agrees within ±5(0) counts of actual setpoint
level.
Analog Output: Factory configured non-isolated output 4-20mA,
8V maximum compliance or 0-10VDC 1kohm minimum load. Span
output set for 0-1000(0) counts, internally adjustable over 500(0) to
2000(0) count span. Accuracy ±1% ±(0.2mA or 0.2V) over operat-
ing conditions. Adjustable range of output is -10% to 100% of F.S.
Relay Output: One normally open below duty contact output per
setpoint. 1A @ 250VAC/30VDC resistive load capacity.
Ambient Temperature Effect: +0.01% of rdg, -0.05˚ per degree.
Temperature Coefficient: ±100 ppm/˚C.
Sensor Wire Effect: 0.01˚C power ohm per conductor.
Broken Sensor: Display flashes overrange for open circuitry input.
Sensor Wire Current: 0.5µA.
Overrange Indication: Display flashes.
Operating Temperature Range: 32 to 122˚F (0 to 50˚C).
Storage Temperature Range: -4 to 185˚F (-20 to 85˚C).
Humidity Range: 0 to 80%, non-condensing.
Power Supply: 115/230 VAC, ±10%, 50/60 Hz.
Power Consumption: 7 W.
Common Mode: Signal common to power ground 1500V peak
DC to 60 Hz. 354V IEC spacing.
Housing: 8 DIN, NEMA 12.
Display: 7 segment red LED 14.2mm high. Decimal point posi-
tioning by internal solder switch. Negative polarity indication by
center segment of left hand display. Alarm indication by 3mm
round red LED displays.
Weight: 1 lb. (500 g).
