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

• 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: 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 “MAX”, “HO” (when the HOLD function is activated), “LO” (low battery condition) and “J”/”K”/”T”.
