Read this before you start using the instrument!

It’s very important that you select Pt-100 mode if you have a Pt-100
sensor and Ni-100 mode if you have Ni-100 sensor, otherwise you will
get inaccurate meter readings. See page 2 how to choose between
Pt-100 and Ni-100.

1. Introduction

SwemaTemp 21 measures temperature with both Pt100 eller Ni100
sensors. SwemaTemp 21 is delivered with two easily replaceable AA
batteries. Standard, alkaline or regular batteries can be used.

2. Technical data

Measuring range: -200…850°C;
IEC 60751 for Pt100 and DIN 43760 for Ni100.
One decimal resolution

Uncertainty (only SwemaTemp 21):
At 0…50°C: ±0,15% read value, min ±0,3°C
At -200…850°C: ±0,2% read value, min ±0,4°C
See probes technical data for uncertainty of SwemaTemp 21
including probe.

The user should correct the measured values with the correction on
the probe calibration protocol to obtain stated uncertainty of measu­rement.

95% coverage probability in non condensing, non moist air, <80%RH, non aggressive
gases.

Battery: 2 x 1,5V IEC LR6, AA
Size: 180x36x82mm
Weight: 380g

3. Start of instrument

• Press the HOLD button to freeze the value. A star will appear on
the screen.

1.

•

Always turn off the instrument before removing the probe.

• When starting the instrument (ON/OFF- button), the
SwemaTemp 21 goes to measuring mode after six seconds.

• If the voltage should drop below 2.4 V, the symbol for low battery
is shown. If the voltage should drop below 1.6 V, the instrument
can’t be turned on.
