The Time 1090 is a high performance instrument designed for use in both the lab and field applications. It simulates and can measure from the most commonly used temperature sensors - thermocouples (8 types) and PT100. In addition it can generate and measure mV and mA.

Thermocouple Measurement and Simulation

Measure and simulate the temperature and mV characteristics of J, K, T, R, S, B, N and E thermocouples.

Cold Junction Compensation

The unit can be operated with or without internal cold junction compensation.

PT100 Measurement and Simulation

Based on 0.3850 alpha probe standard. Range is -200°C to 700°C.

Measurement and Source (µV, mV, and mA)

Measurement ranges are 0 to +/-30mV and 0 to +/-60mA. Source ranges are 0 to +/-80mV and 0 to +80mA.

Temperature Units Selection

The display can be easily changed from °C to °F. The equivalent uV (thermocouples) and ohms (PT100) can also be shown.

24V Process Loop Drive Mode

A process loop can be driven at 24V and up to 60mA by selecting the ‘Milliamp Source’ mode and setting it at 60mA (or a lower level if required).

Inching (Incrementing/Decrementing)

The unit has a general-purpose inching function. This adjusts the output in fixed increments of temperature (thermocouples only) or voltage or current. The set-up menu gives a the user a choice of three levels of increment i.e. 0.1, 1 or 10 for °C/°F, or 1, 10, or 100 uV/uA for voltage/current. The lowest of these represents the highest setting resolution and provides the most precise control of the output.  This is especially useful for calibrating thermostat controllers that have tight specification on hysteresis.

Memory Recall and Step/Auto-Step Functions

Up to 10 values can be stored in the unit’s non-volatile memory and they can be recalled at any time. The user can also manually step through them in sequence using the step key. Continuous stepping (auto-step) is also available at any user selectable rate between 1 & 10 seconds/step.

Power is via an internal high capacity rechargeable metal hydride battery that can be recharged from the supplied external mains charger. An auto power-down feature helps conserve battery life by switching off the instrument if inactive for over 5 minutes. This feature can be disabled if not required.
