1. INTRODUCTION
1.1 Introducing the Temp JKT
Thank you for purchasing the Temp JKT meter. This economical microprocessorbased handheld meter works with type J, type K and type T probes for a wide
temperature measurement range:
• Type J probes (iron-constantan) offer a wide range of –200 to 1000 °C / 328 to 1832 °F; use in reducing environments
• Type K probes (chromel-alumel) offer the widest range of –250 to 1372 °C
/ -418 to 2502 °F; use in oxidizing environments
• Type T probes (copper-constantan) of range of –250 to 400 °C / -418 to
752 °F; good for ambient and sub-freezing measurements
The Temp JKT meter features:
• Large LCD for clear and easy reading
• Readings in
o
C and oF (selectable)
• Minimum and maximum temperature display
• Minimum and maximum hold mode
• Low battery indicator
• Hold function, freezes measured reading
• User calibration - offset adjustment
• Built-in memory backup; calibration and other information remain if battery

ON / OFF, CAL, HOLD / ENTER,
oC/o
F, MAX/ or MIN/ key and J-K-T keys.
ON/OFF: Powers meter on and shuts the unit off.
Meter directly enters measurement mode when
you turn it on.
CAL: Allows temperature calibration of the
meter.
HOLD/ENTER: Freezes the measured reading;
confirm calibration value.
MAX/ (UP) or MIN/ (DOWN): Momentarily
displays meter’s maximum and minimum
temperature; enter maximum or minimum hold
mode; scroll up and down in calibration mode.
oC/o
F: Switches between oC and oF in
measurement mode.
J-K-T: Switches between J, K and T
thermocouple measurement mode.
2.2 Description of LCD Annunciators
The EcoScan Temp JKT meter has a large custom LCD that consists of 4-digit
segments and operation annunciators for
o
C and oF. Other indicators include “MIN’,
“MAX”, “HO” (when the HOLD function is activated), “LO” (low battery condition)
and “J”/”K”/”T”.
